You can differentiate and integrate n times but what if n is not a whole number? This generalisation of calculus was introduced and discussed on askNRICH by some school students.

Here explore some ideas of how the definitions and methods of calculus change if you integrate or differentiate n times when n is not a whole number.

Fractional calculus is a generalisation of ordinary calculus where you can differentiate n times when n is not a whole number.

Consider these analogies for helping to understand key concepts in calculus.

How would you sort out these integrals?

Get started with calculus by exploring the connections between the sign of a curve and the sign of its gradient.

Can you hit the target functions using a set of input functions and a little calculus and algebra?
