36%= 36/100

Divide it by 2, the answer will be 18/50.

It can then be divide by 2 again and getting to the answer of 9/25. 

This is a classic 2-D projectile question.

The best way to solve this problem is to split the velocity into its x and y components.

In the x-direction a projectile has no forces acting on it...

First must recall the formula, of pi multiplied by the integral of y²

After this, the correct integration should be applied, using an appropriate method that the student has learnt

In simple differentiation, we can use the fact that if y= x^n, dy/dx is equal to nx^(n-1). In other words, multiply the x term by the power, then decrease the power by 1. Here we have 2 terms so approach ...

To begin with, lets rewrite the equation in a way which is easier to understand by making y the subject and multiplying out the brackets:

y = x² - 4x - 14

this looks significantly...
