The slope intercept form calculator determines the point slope between two points in the Cartesian coordinate system. To find this equation, we need the slope and the y-intercept. The slope is the ratio of the vertical change between two points, and the horizontal change between the same two points.

To calculate the slope, we use the formula: m = (y2 - y1) / (x2 - x1), where m is the slope of the line, and (x1, y1) and (x2, y2) are the two points on the line.

The y-intercept is where the line crosses the y-axis, and its x-coordinate is always 0. To find the y-intercept, we can use the equation y = mx + b, where m is the slope, and b is the y-intercept.

Given the equation of a line in slope-intercept form, y = mx + b, we can find the slope and the y-intercept. The slope is the coefficient of x, and the y-intercept is the constant term.

For example, given the equation y = 2x + 3, the slope is 2, and the y-intercept is 3.

To convert the slope-intercept form to the point-slope form, we can use the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line, and m is the slope.

For example, given the equation y = 2x + 3, we can rewrite it in point-slope form as y - 3 = 2(x - 0), where (0, 3) is a point on the line.

The point-slope form calculator can also be used to find the equation of a line given two points. We can use the formula m = (y2 - y1) / (x2 - x1) to find the slope, and then use the equation y - y1 = m(x - x1) to find the equation of the line.

For example, given the two points (1, 2) and (3, 4), we can find the slope as m = (4 - 2) / (3 - 1) = 1. Then, we can use the equation y - 2 = 1(x - 1) to find the equation of the line.

The slope intercept form calculator is a useful tool for finding the equation of a line in slope-intercept form, given two points or the slope and the y-intercept. It can also be used to convert the slope-intercept form to the point-slope form, and vice versa.

In addition to the slope intercept form calculator, there are other forms used to express the equation of a line, such as the standard form and the point-slope form. The standard form is Ax + By = C, where A, B, and C are constants. The point-slope form is y - y1 = m(x - x1), where (x1, y1) is a point on the line, and m is the slope.

Each form has its own advantages and disadvantages, and the choice of which form to use depends on the specific problem and the given information. The slope intercept form is one of the most common forms used to express the equation of a line, and it is widely used in many fields, such as physics, engineering, and economics.

In conclusion, the slope intercept form calculator is a useful tool for finding the equation of a line in slope-intercept form, given two points or the slope and the y-intercept.

The calculator can also be used to find the slope and the y-intercept of the line, given the equation in slope-intercept form.

The point slope form calculator is another useful tool that can be used to find the equation of a line. It uses the formula y - y1 = m(x - x1), where (x1, y1) is a point on the line, and m is the slope.

To use the point slope form calculator, simply enter the given values, such as the point and the slope, and the calculator will give the equation of the line in point-slope form. The calculator can also be used to find the slope and the y-intercept of the line, given the equation in point-slope form.

In addition to the slope intercept form calculator and the point slope form calculator, there are other calculators that can be used to find the equation of a line


pi goes on and on and on …
And e is just as cursed.
I wonder: Which is larger
When their digits are reversed?
Chebychev said it and I’ll say it again:
There’s always a prime between n and 2n.

Come on folks let’s integrate!

A mathematician confided
That the Moebius band is onesided
And you’ll get quite a laugh
If you cut one in half
‘Cause it stays in one piece when divided.

A mathematician named Klein
Thought the Moebius band was divine
Said he: “If you glue
The edges of two
You’ll get a weird bottle like mine.”

The Moebius strip is a pain,
When you cut it again and again,
But if you should wedge
A large disk round the edge
Then you just get a projective plane.

If you have a crosscap on your sphere,
And you give it a circleshaped tear,
Then just shake it about
And untangle it out
And a Moebius strip will appear!

There was young maiden named List
Whose mouth had a funny halftwist.
She’d turned both her lips
Into Moebius strips…
‘Til she’s kissed you, you haven’t been kissed!

There was a young fellow named Fisk,
A swordsman, exceedingly brisk.
So fast was his action,
The Lorentz contraction
Reduced his rapier to a disc.

A conjecture both deep and profound
Is whether the circle is round;
In a paper by Erdos,
written in Kurdish,
A counterexample is found.

A challenge for many long ages
Had baffled the savants and sages.
Yet at last came the light:
Seems old Fermat was right–
To the margin add 200 pages.

A calc student upset as could be
That his antiderivative didn’t agree
With the one in the book
E’en aft one more look.
Oh! Seems he forgot to write the “+ C”.

A graduate student from Trinity
Computed the cube of infinity;
But it gave him the fidgets
To write down all those digits,
So he dropped math and took up divinity.

A mathematician called Bird,
Had students who thought him absurd.
There were cries of derision
When he said long division,
Meant one into one made a third.

A mathematician called Rumbold,
One day, quite by accident, stumbled
On the Meaning of Life,
Then went on, for his wife,
To find out why all her apple pies crumbled.

To a tightrope walker named Zekund
The a due to gravity beckoned.
His performance was great
At about 9.8
Meters per second per second.

Consider the pitiful plight
Of a runner who wasn’t too bright.
For he sprinted so fast,
That he vanished at last
By redshifting himself out of sight.

In the nearlight speed spaceship I’m in,
I went rocketting off from my twin;
But since I’ve been away
I’ve aged hardly a day
And just look at the state that he’s in!

There once was a prof, Dr. K.,
Who taught calculus everyday.
From dawn until noon,
Integrating to the moon.
To him, derivatives were okay.

There’s a leatherclad separatrix,
a vectorvalued dominatrix
who divides a phase plane
into pleasure and pain
when she gets hold of more than one matrix.

Jack the mathematician
Had a very strange mission.
The problems he wrote,
He often would gloat,
Sent many a student awishin.’

There was a prof named Kowalski
Who taught all this calculus to me.
On the final — no pass;
I must retake the class.
Why, we should all be so lucky.

Despite all the might fine teachin,’
I can’t help but find myself thinkin’
That Calculus I
Will be much more fun
The second time o’takin’.

Along cam Sir Isaac Newton
Doin’ mathematical computin’.
One day he contrived
To antiderive
When findin’ signed areas is suitin’.

There once was a user named Fred,
Who one day used grep, awk, and sed.
He parsed a huge text stream,
Used regexps to the extreme,
Now his file’s tail is its head.

Euler’s Equation:
Here are a few limericks about this one.
I used to think math was no fun,
‘Cause I couldn’t see how it was done.
Now Euler’s my hero,
For I now see why 0
Equals e^{ pi i} + 1.

The Pythagorean Theorem:
A triangle’s sides a, b, c,
With a vertex of 90 degrees,
If that vertext be
‘Tween sides a and b,
The root a^{2} plus b^{2} is c.

Equation 1:
A Dozen, a Gross and a Score,
Plus three times the square root of four,
Divided by seven,
Plus five times eleven,
Equals nine squared and not a bit more.

Equation 2:
Integral vsquared dv
From 1 to the cube root of 3
Times the cosine
Of three pi over 9
Equals log of the cube root of e.

Equation 3:
One over point oneohtwothree,
When raised to the second degree,
Divided by seven
Then minus eleven
Is approximately equal to e.

Equation 4:
Th’integral from esquared to e
Of 1 over v dot dv,
When raised to the prime
Between five and nine,
Is e to the i pi by 3.

Equation 5:
The integral from naught to pi
Of sinesquared of 2 phi dphi,
When doubled and then
Not altered again,
Is log (minus 1) over i.

Equation 6:
To find Euler’s Gamma of three,
Integrate to infinity
From zero, dx
xsquared on exp(x),
Or three bang divided by three.

Equation 7:
‘Cause phisquared less phi, minus 1,
Is exactly equal to none,
The golden mean phi,
Which so pleases the eye,
Is half of root 5 add on one.

Equation 8:
The square root of minus 2 pi
On th’square root of inverse sine phi;
All that need be done
Is let phiequal one:
It’s twice exp of i pi on i.

Figure 1:
If a circle through B, like so,
Has arc AD with center O,
The angle at B,
Wherever B be,
Is half of the angle at O.

Figure 2:
A body with mass m kg
Feels a force of magnitude T.
When its weight t’wards the ground
Is added it’s found
To speed up at T on m, less g.

Proof 1.
If a=b (so I say)
And we multiply both sides by a
Then we’ll see that asquared
When with ab compared
Are the same. Remove bsquared. Okay?
Both sides we will factorize. See?
Now each side contains a minus b.
We’ll divide through by a
Minus b and olé
a+b=b. Oh whoopee!
But since I said a=b,
b+b=b you’ll agree?
So if b = 1
Then this sum I have done
Proves that 2 = 1.

Piems
There is in mathematical circles (ha!) a great and lengthy tradition of making mnemonics to memorize the digits of pi:
pi = 3.14159 26535 89793 23846 26433 83279 502….

In a traditional pi mnemonic, such as the one above, the number of characters in each word is used to represent a digit of pi, with the ocassional 10, 11, 12, or 14digit word denoting two digits of pi.

Of digits large and small,
teaching diameter’s precise relations,
And we can remember ‘tall.

An artful charm, for tasks availing,
Intricate results entailing.

For circumscribing a round enclosure or circle, every man
might remember ingenious numbers measuring one by one
diameter into circle or circle upon its own diameter…

3.14159 26535 89793 23846 26433 83279
See, I have a rhyme assisting
My feeble brain, its tasks sometime resisting,
Efforts laborious can by its witchery
Grow easier, so hidden here are
The decimals all of circle’s periphery.

Sir: I wish I could recapture my memory about Sir
Jeans’ diabolic mnemonics! However, invention
now of any reliable easy phrase is beyond what shy
and fumbling aid my present intellect gives.

May I have a month, professor,
To figure these, you brain assessor?
Calculate, student, calculate now!
As the figuring gets longer,
My friend, hope you get stronger
And no figures incorrect allow!

You I sing, O ratio undefined
By strict assay and lined,
Sequence limitless. Stunned regarding you,
We see eternity — alas — unwind
In random cast and rue,
Dejected out of measure, reckoning blind.

May I tell a story purposing to render clear
the ratio circular perimeterbreaths, revealing
one of the problems most famous in modern days,
and the greatest man of science anciently known.

3835 digits of pi…
Of course, the all out winner, a massive mnemonic encoding 3835 digits of pi, is Michael Keith’s Cadaeic Cadenza, a fourteen chapter collection of digitmindful paraphrasings of entire works of literature, including Edgar Allan Poe’s The Raven, Shakespeare’s Hamlet, Lewis Carroll’s Jabberwocky, and Carl Sandburg’s Grass, among others.

4:45 AM
I keep writing things down
and then losing the pieces of paper
because individually the work isn’t any good
but collectively it’s enough to scare Clive Barker.

Now I study sequences and series
and spend much of my time
showing where things tend as
they approach infinity.
Infinity is strange.
There is no concept of
next to within its grasp
and yet it can be countable.
I keep studying math
because to me I have always
found myself immensely satisfied
when I come up with the right answer.

Now it seems the further I go
I find myself with less answers
and more questions and I only
hope that math will know.

I like the quiet of night
when the sleeping world
reaches its serendipitous pinnacle
and I can listen to no one talk.
In that delicate moment of the
restless yearning for rest I can
see answers on the insides of
my eyelids written in bright
flashes of neon light.

The few times that I
switch on the lamp to write
them down, they are no longer
there to be seen.

4:45 A.M.
November 3, 1999
Any questions?

The professor  Students 1, 2, and 3
Now then, are there any questions, Any problems, any questions? If there are none, then I am done, And I can bid you all good day.

Ha, he asks if there are any questions. Holy smoke have I got questions! I’ve got a ton, and every one, Would take him half a day to do.

The derivative song
(To the tune of “There’ll Be Some Changes Made.”)
Introductory Dialog, spoken by the Professor:
To cover that great theory would be my fondest hope,
Were it not that of this course it’s far beyond the scope.

You take a function of x and you call it y,
Take any xnought that you care to try,
You make a little change and call it delta x,
The corresponding change in y is what you find nex’,
And then you take the quotient and now carefully
Send delta x to zero, and I think you’ll see
That what the limit gives us, if our work all checks,
Is what we call dy/dx,
It’s just dy/dx.

Did I miss anything?
Nothing. When we realized you weren’t here
we sat with our hands folded on our desks
in silence, for the full two hours.

Everything. I gave an exam worth
40 percent of the grade for this term
and assigned some reading due today
on which I’m about to hand out a quiz
worth 50 percent.

The drinking song (for mathematicians)
Chorus
We drink to mathematics, upon whose structure lies
The physics of both space and time, and why the butter flies.

Rene from Chartres was a man who had it all worked out.
He said, “I think therefore I am — of this there is no doubt!
And by some lines in space you can all points therein describe,
So with that thought I think I shall another beer imbibe”

Pierre de Fermat out of France, he was a gambling man.
He said “I read these books of mine to find out all I can.
“x^{n} plus y^{n}‘s not z^{n} if n does exceed two,
But the margins of this book cannot contain this wond’rous proof!”

An apple fell and Newton saw it plummet to the ground.
He said “I wonder what doth make the Moon to go around?”
Gravity was born that day, and so was calculus,
With its fluxions and its fluents and its dots to torment us.

Bernoulli: father, son, and brother, and an uncle too.
Daniel was a relative, a cousin once removed.
Math and physics gained a lot, for they fought endlessly,
And nothing breeds success so much as sibling rivalry!

Euler did believe in God, just like his fellow man.
Diderot the atheist said “Prove God if you can!”
“Sir, (a + bn) over n is x so therefore God exists!”
And Diderot could not refute a proof as good as this.

Joseph Louis Lagrange wrote a book full of mathematics.
In English it would be the Analytical Mechanics.
He said “Look high and low, you’ll find no pictures here!
So kind sir would you pour for me another pint of beer!”

Marquis de Laplace did write some works on motions up in heaven.
He started work when but a lad of only ten and seven.
Napoleon said “I see no sign of God in this!”
Laplace replied “I have no need for that hypothesis.”

Karl Friedrich Gauss had a choice at one year ‘ere his score,
To study mathematics, or words forevermore.
With compass and straightedge, he made his choice anon:
He went around and then inscribed a septendecagon.

Cauchy and Bolzano thought that math was in a mess.
Separately they sought to make it much more rigorous!
Bolzano was Bohemian, and Cauchy came from France.
And with their work analysis continued its advance.

Evariste Galois did write the theory of the group.
And with his knife did toast the King before the course of soup.
And at my age been laid to rest a dozen years or more.
So unto algebra I drink this next drink that I pour.

Linear equations can be solved by anyone.
The cubics and quadratics and the quartics have been done.
Abel said “The quintics cannot likewise fall!
They cannot be resolved by means of radicals at all!”

Riemann said that parallels need not exist in space.
Lobachevsky said that two or more could be in place.
The axioms of Euclid, which give us only one,
Cannot describe the space near massive bodies like the sun!

Kronecker thought numbers should be things you can count on.
To root of 2 and rationals, he said “Vile things, begone!
Numbers should be whole! Let’s get rid of the reals!
And in their place we’ll substitute the theory of ideals!”

Cantor showed that aleph_{0} can count the integers.
And aleph_{1} the reals, and aleph_{2} the curves.
For alephthreeormore, we’ve got no use at all.
So let us sing of aleph_{0} beer bottles on the wall.

Banach, Tarski and Sierpinski were a bunch of Poles
Creators of pathologies, like gaskets full of holes!
“If you cut a sphere just so, from one you shall make two!”
(To comprehend this proof you need another pint of brew!)

von Neumann was a man of math, from Hungary he came.
He did his work with automats and theories of the game.
He said “By minimax, you might as well coins flip!
“So you can play your game while I will have another sip!”

The saga of mathematics has not yet in full been told.
The story, it goes on and on, it’s six millenia old.
And yet I fear this song, has gone on long enough.
So take my glass and fill it with some alcoholic stuff….

The drinking song (for philosophers)
Immanuel Kant was a real pissant
who was very rarely stable.
Heidegger, Heidegger was a boozy beggar
who could think you under the table.

David Hume could out consume
Wilhelm Friedrich Hegel,
And Wittgenstein was a beery swine
who was just as sloshed as Schlegel.

There’s nothing Nietzsche couldn’t teach ya
‘Bout the raisin’ of the wrist.
Socrates himself was permanently pissed.
John Stuart Mill, of his own free will,
After half a pint of shandy was particularly ill.

Plato, they say, could stick it away,
Half a crate of whiskey every day!
Aristotle, Aristotle was a bugger for the bottle,
And Hobbes was fond of his Dram.

And Rene Descartes was a drunken fart:
“I drink, therefore I am.”
Yes, Socrates himself is particularly missed;
A lovely little thinker, but a bugger when he’s pissed.

The electron in gold
There was an electron in gold
Who said, “Shall I do as I’m told?
Shall I snuggle down tight
With a brief flash of light
Or be Auger outside in the cold?”

Epigram
Nature and Nature’s laws lay hid in night.
God said, “Let Newton be!” and all was light.

It did not last: the Devil howling “Ho!
Let Einstein be!” restored the status quo.

Euclid drew a circle
Old Euclid drew a circle
On a sandbeach long ago.
He bounded and enclosed it
With angles thus and so.

Lines inspired by a lecture on extraterrestrial life
Some time ago my late Papa
Acquired a spiral nebula.
He bought it with a guarantee
Of content and stability.

Lobachevsky
For many years now, Mr. Danny Kaye, who has been my particular idol since childbirth, has been doing a routine about the great Russian director Stanislavsky and the secret of success in the acting profession.

Who made me the genius I am today,
The mathematician that others all quote,
Who’s the professor that made me that way?
The greatest that ever got chalk on his coat.

One man deserves the credit,
One man deserves the blame,
and Nicolai Ivanovich Lobachevsky is his name. Oy!

Nicolai Ivanovich Lobache…
I am never forget the day I first meet the great Lobachevsky. In one word he told me secret of success in mathematics: Plagiarize!

The New Math
(For the stage)
Some of you who have small children may have perhaps been put in the embarrassing position of being unable to do your child’s arithmetic homework because of the current revolution in mathematics teaching known as the New Math.

You can’t take three from two,
Two is less than three,
So you look at the four in the tens place.
Now that’s really four tens
So you make it three tens,
Regroup, and you change a ten to ten ones,
And you add ’em to the two and get twelve,
And you take away three, that’s nine.

Ode to Z
Inspired by “Trees,” by Joyce Kilmer.
I think that I shall never see
An aleph set as nice as Z.
A principal ideal domain,
The ring of things that keeps me sane.

Oh! The places waves go!
Modeled on “Oh! The Places You’ll Go,” by Dr. Seuss.
Congratulations!
Today is your day.
You’re off to learn many
Great things about waves!

Optimization
First grasp your objective and all the constraints,
Then write your equations, and start your complaints.
Reduce to one variable, find the realworld domain.
Then find local extrema — use calc to avoid strain!

Pereant
I’ve proved some theorems, once or twice,
And thought that they were rather nice.
My presentations were rejected
By referees who had detected
Those theorems that I thought my own
In journals I had never known,

Perils of modern living
From the San Francisco Chronicle, 1956:
A kind of matter directly opposed to the matter known on earth exists somewhere else in the universe, Dr. Edward Teller has said…

He’s teaching her arithmetic,
He said it was his mission,
He kissed her once, he kissed her twice
And said, “Now that’s addition.”

If you give me your attention, I will tell you what I am.
I’m a brilliant math’matician – also something of a ham.

Relativity
(To the tune of “Personality” by James Van Heusen.)
Introductory Dialog, spoken by the English major:
But I think this course underemphasizes the importance of relativity, and I would like you to hear a few words in its behalf.

Einstein was the first who stated,
He was the first who dared:
Mass and energy are related,
By E = mc^{2}.

The slide rule song
Introductory Dialog, spoken by the Professor: Now to get on with the class —
I give you now the Section Man,
This friend of yours and mine’ll
Offer you some very good advice about the final.

Take away your billion dollars

From all the land are men at hand, their wisdom to exchange.

Kendra has $5.70 in quarters and nickels. She has 12 more quarters than nickels. Let's denote the number of nickels as N and the number of quarters as Q. We know that Q = N + 12. The total value of the coins is $5.70. Since a nickel is worth $0.05 and a quarter is worth $0.25, we can set up the equation: 0.05N + 0.25Q = 5.70. Substituting Q = N + 12 into the equation gives 0.05N + 0.25(N + 12) = 5.70. Simplifying the equation yields 0.05N + 0.25N + 3 = 5.70. Combining like terms results in 0.30N + 3 = 5.70. Subtracting 3 from both sides gives 0.30N = 2.70. Dividing both sides by 0.30 gives N = 9. Since Q = N + 12, Q = 9 + 12 = 21. Therefore, Kendra has 9 nickels and 21 quarters.


# Relationship between Z Score and Distribution Critical Values

The critical value of Z (z*) is used when the sampling distribution is normal. It represents the probability that a relationship between two variables exists. To find a critical Z value, we need to consider the confidence level and the type of hypothesis test being conducted.

## Hypothesis Testing with the Z Score

In a 2-tailed hypothesis test, the calculated Z score must be farther away from the mean than the critical value. The alpha level is split across both tails, resulting in two critical values and two rejection regions. The area between the rejection regions represents the population.

When deciding between a one-tailed and two-tailed test, it's essential to consider the direction of the effect. A one-sided test is used when the effect is suspected to be in one direction, while a two-sided test is used when the direction is unknown. Failing to reject the null hypothesis does not mean the null hypothesis is true.

## Z-Statistics vs. T-Statistics

To construct a confidence interval, we take the statistic (e.g., sample mean) and add or subtract a certain number of standard deviations. The number of standard deviations is determined by the critical value, which is then multiplied by the standard deviation of the statistic. In cases where the population parameter is unknown, we use the standard error of the statistic instead.

## What is a Z Score? What is a p-value?

A Z score represents the number of standard deviations from the mean. To calculate a Z score, we need to know the critical value (z*). The critical value can be looked up in a Z-table or calculated using a calculator function. However, it's crucial to be careful when using Z-tables or calculator functions, as they may provide different types of areas (e.g., total area from negative infinity to z standard deviations above the mean).

When using Z-tables, we need to consider the type of area being provided. Some Z-tables give the total area from negative infinity to z standard deviations above the mean, while others may provide different types of areas. By understanding how to find and interpret critical Z values, we can make informed decisions in hypothesis testing and confidence interval construction.


To find parametric equations for the curve of intersection of the cylinders x^2 + y^2 = 1 and x^2 + z^2 = 1, we need to analyze the given equations.

First, we notice that both equations are equal to 1, so we can set them equal to each other: x^2 + y^2 = x^2 + z^2.

Simplifying the equation, we get y^2 = z^2. Taking the square root of both sides, we get y = ±z.

Now, we can substitute y = ±z into one of the original equations, x^2 + y^2 = 1. We get x^2 + (±z)^2 = 1, which simplifies to x^2 + z^2 = 1.

We can parameterize the equation x^2 + z^2 = 1 using the parametric equations x = cos(t) and z = sin(t), where 0 ≤ t ≤ 2π.

Since y = ±z, we can write the parametric equations for y as y = ±sin(t).

Therefore, the parametric equations for the curve of intersection are x = cos(t), y = ±sin(t), and z = sin(t), where 0 ≤ t ≤ 2π.

To graph the parametric equations, we can use a 3D graphing calculator or software, such as 3D Calc Plotter. We can graph the two surfaces, x^2 + y^2 = 1 and x^2 + z^2 = 1, and then graph the parametric equations for the curve of intersection. We can use different colors for each parametric curve.

Note: The original problem asked to print out the graph, but since we are working in a text-based format, we cannot provide a printed graph. However, we can describe the process of graphing the parametric equations using a 3D graphing calculator or software.
