# Clearing the confusion of the area
In the example 1:
They are finding the area as $8$ $\sqrt[2]{30}$. But, I am finding $8$ $\sqrt[2]{15}$.
I have done $\sqrt[2]{16\times5\times8\times3}$
Then,
Breaking it up,

$\cos 18^\circ$ $=$ $\dfrac{\sqrt{10 + 2\sqrt{5}}}{4}$ $=$ $0.951056516\ldots$
## Proof
Theoretically, it is not possible to find the value of cos of $18$ degrees directly. Alternatively, it can be found from the value of sine $18$ degrees. Therefore, use $\sin 18^\circ$ value and transform that value into... |

# How do you solve the linear equation x+3y=2 and -x+y=1 using the substitution method and are they dependent, independent, or inconsistent?
Oct 22, 2017
$x = - \left(\frac{1}{4}\right) , y = \left(\frac{3}{4}\right)$
They are dependent and consistent.
#### Explanation:
$x + 3 y = 2$

Percentage
1.
Three candidates contested an election and received $$1136, 7636$$ and $$11628$$ votes respectively. What percentage of the total votes did the winning candidate get?
Total number of votes polled $$= (1136 + 7636 + 11628) = 20400.$$
$$\therefore$$ Requried percentage $$= (\frac{11628}{20400} \tim... |
In This Unit of Study…
The concept of volume extends from an understanding of area; the number of unit cubes covering the bottom layer are built up by adding layers on top until the solid is filled. Students reason that volume is the number of unit cubes needed to fill a solid figure without gaps or overlaps. As stude... |
# Problems from Almost direct integrals
Compute the integral $$\displaystyle\int\dfrac {x \sin (x^2)}{1+ \cos^2 (x^2)} \ dx$$
See development and solution
### Development:
We will use the following procedure:
• Observe what type of almost direct integral the given expression could be. To do so, we have to identify... |
## Integration Using Partial Fractions
To integration an expression of the form
$\frac{p(x)}{q(x)}$
where the degree of
$p(x)$
is less than the degree of
$q(x)$
write the expression as partial; fractions as much as possible and then integrate using other methods.
Example:
$\int \frac{2x-1}{x^2-4x-5} dx$
$\int \frac{2... |

Dividing Fractions
To divide fractions, we need to know these 3 basic parts. Suppose we want to divide by , the setup should look like this.
• Dividend - the number being divided or partitioned by the divisor. It is found to the left of the division symbol.
• Divisor - the number that is dividing the dividend. It is ... |
