Core 1 and 2 – Differentiation to find stationary points

Again as yesterday Core 1 and Core 2 are the same except the Core 2 questions have more complicated powers of x. It’s worth noting again that we can’t cover everything in these posts. There are some questions on increasing and decreasing functions and some applications of stationary points that I’ve not covered here. You will need to look through past papers yourself to ensure you can do all the questions.

Core 1 and 2 – Differentiation to find tangents and normals

Core 1 and Core 2 differentiation are very similar. The only real difference is that in Core 2, x can have negative and fractional powers. There are two videos and two questions below. One of each is a Core 1 questions and one of each is a Core 2 question.
