We know that sinx/cosx = tanx. Therefore we can write sinx - cosx = 0 as sinx = cosx . By diving both sides by cosx, we get tanx = 1. By taking tan inverse of both sides, we can see that for 0≤x≤360, we g...

We can factorise the quadratic equation by noting that two numbers which multiply to get 24 and that add to get -10 are: -6 and -4. Therefore, we get (X-6)(X-4)=0 and we can solve for X to get X = 6 or X ...

I don't know what gcse entails but I'm certain I could teach it

1.Here the first task in this is to be able to identify the form of this quadratic polynomiala^2 - b^2This format is called the difference between two squares When you ge...

There are several ways we can rearrange algebraic formulae in order to change the subject. Changing the subject basically means changing the variable (letter) that we are trying to find out, so getting th...
