consider S defined by
z = f(x,y) = x^2 + 4(y - 1)^2
1) Graph the level curves of f in the (x,y) plane. So will this be a 2D drawing, if/if not how do i do this? What will it look like?

Range and Domain
1. Graph the parabola $y=x-x^2$. Then find the domain and range of $f(x)=sqrt(x-x^2)$.
2. Graph the parabola $y=3-2x-x^2$. Then find the domain and range of $g(x)=sqrt(3-2x-x^2)$.

be to compute the value of x by $x^2-1=5x$. B... | 4 | [

Finding f
I need help getting the antiderivative.
Find f.
f '(x)= (3x + sqrt(x) + 4)/(x^2); f(1)= -1
I got: f '(x)= 3/x + 1/x^(3/2) + 4/x^2
I broke it up so each piece is under x^2.

Solve a dilemma
Pls solve a following dilemma
a=b
a^2=ab Multiplying both sides by a
a^2-b^2=ab-b^2 Subtracting b^2 from both sides
(a+b)(a-b)=b(a-b)
(a+b)=b
b+b=b
2b=b

Limit[e*w*L/Sqrt[R^2 + (w*L - 1/(w*C))^2], w -> Infinity]
So I need to take the limit of
e*w*L/Sqrt[R^2 + (w*L - 1/(w*C))^2] as w approaches infinity
So in Mathematica it would l... | 5 | [

Hi,
I need to evaluate intergral (-inf, inf) of S(x-y, t)dx where y element R and where s(x, t) = (1/2sqrt(pi*k*t))e^((-x^2)/4kt). You are supposed to use the fact that intergral (-inf, i... | 5 | [

Absolute convergence of the beta function
Determine the values of the complex parameters $p$ and $q$ for which the beta function $\int_0^1 t^{p-1} (1-t)^{q-1}dt$ converges absolutely.

Hash Tables
3.4 Hash Tables
If keys are small integers, we can use an array to implement a symbol table, by interpreting the key as an array index so that we can store the value associated with key i in array position i. In
