We all make silly mistakes when in comes to Maths, so here are some common mistakes to help you out. 1. Partial Fractions: Many students think x+2/(x+1)^2 becomes A/(x+1) + B/(x+1) This ...

f'(x)=2x+5

note that f'(x)=nx^n-1

so 2x is originally x² as this is 2x^2-1

and 5 is originally 5x^1-1

 f(x)= x²+5x+c...

Firstly, use the factor theorem to determine one factor. Substitute factors of 24 into the equation, beginning at plus or minus 1 and then increasing. The first factor found will be -2, therefore (x+2) is...

When told to find angles when equations are involving sin,cos or tan at a level a range will be provided. You have to find all the angles within the given range. Multiple angles will be found as there wil...

I would recommend that all A-level students should attempt all previous exam papers at least once. This is to pick up on common tricks that the examiner uses and in most cases these tricks keep coming up ...
