Finding areas by integration

This unit looks at
how to calculate the area bounded by a curve using integration.

Volumes of solids of revolution

We sometimes need to calculate the volume of a solid which can be obtained by
rotating a curve about the x-axis. There is a straightforward technique
which enables this to be done, using integration. This unit will explain how.
