Differentiating a circle

Differentiating a circle:
1 minute video showing how to differentiate a circle. This video is aimed at A level maths (typically covered as a second year topic for those studying the single maths A Level). This video builds on ides from year 12 and 13 differentiation allowing us to differentiate complicated functions (many-to-many) and recognize a gradient function.

In a nutshell: Finding the gradient function of a circle can be done in a variety of ways…
• We can use implicit differentiation to differentiate both x and y.
• We can re-arrange to make y the subject and then use the chain rule to differentiate
