Quick question on C1 & differentiation Watch

1. Okay, just a quick question. I've been going through C1 ever since I finished my GCSE maths exam so apologies if this seems like a silly question.

Is the second derivative on C1 exams? I'm really confused as to what it's used for and why. It was only briefly mentioned when I covered differentiation.

Exam board?

It's not part of Edexcel C1. It becomes useful in C2 where you can use it to check the nature of a stationary point.

Yes it's edexcel, thanks!

Being able to find the second derivative IS on Edexcel C1 but, as Notnek said, doing anything useful with it (characterising stationary points) comes in C2.

Yes you are completely right of course.

You would think someone who teaches C1 regularly would remember that
