This might be hard at first, but if you work through step by step you'll get there!

Start by getting rid of the fraction, multiply both sides by (3x-1) to get y(3x-1) = 2(1+x)

This question is about rearranging the equation so that we have all the unknown values on one side, and all the known values on the other side.To start, we want to put all the x values on one side, and al...

This is an algebraic fraction. There is more than one way of solving this expression, but the simplest is to factorise both the top and the bottom quadratic expressions.Firstly we shall simplify the top e...

The integral of sine is pretty easy to remember as it is -cos + C. However you need to be able to prove this, without using the integral of cosine. This method uses sines exponential form.

Here you need to use two formulae; one for the surface area of a sphere (4πr²) and one for the area of a circle (πr²).

First the surface area of the 6cm radius spher...
