A-Level Maths – Differentiation from First Principles

We need to be able to differentiate a number of functions from first principles. This is a fairly standard proof the follows the same format each time.

As such these can be fairly easy marks to gain in the exam so it is well worth spending 10 minutes now getting to grips with differentiation from first principles!

In the video below we cover how to prove the derivative of a function from first principles. The worksheet on this page provides a number of similar questions for you to practice including past exam questions. We would thoroughly encourage you to have a go at some if not all of these questions as part of your exam preparation.
