It may sound cliched - however to get the highest marks in Maths at A levels means going beyond your exam board! Do not just rely on the past paper questions from your exam board but try a few papers from th...

the equation: x 3 - 6x 2 + 11x -6 Becasuse it intersects at the x axis, y=0 so we set the equation equal to 0. x 3 - 6x 2 + 11x -6 =0 we know it intersects the x axis at 1 and so (x-1) is a factor of that eq...

The main thing to remember with implicit differentiation is to differentiate each thing as you see it. Don't worry about rearranging the equation until you have differentiated everything first. Say you have ...

Let log a be some number A and log b be some number B now the natural log of something is the equivalent of saying a=e^A and b = e^B So a*b = e^A * e^B which by rules of indices = e^(A+B) Therefore log(ab) =...

Firstly, in order to solve this problem we would need to differentiate f(x) to get f'(x). To differentiate this we would use the quotient rule. The quotient rule is that: dy/dx = (V.dU/dx - U.dX/dx) / V^2 wh...
