Differentiation at A level is a method of working out the gradient of curves that aren't straight lines. If you have a function that is non-linear, which means any function that isn't in...

The first step in solving the equation is to find the stationary points of the function, these are the points where the gradient is equal to zero. In order to find these points, first differentiate using ...

It's easier if we first visualise the function on a graph, then we can see in which regions it is negative. From there we can see which integer values lie in this region. A positive quadratic function has...

Well how much do you understand about it? Have you got any ideas at the moment?
(Then I would work through the multi-staged question with them)
1) What equation do you use to work out these type...

You want to make the equations equal one another. If both equal y it can be written like this: x²+2x-2=4x+6Then simplify by putting the terms on one side and equaling 0: x²-2x-8Now p...
