### Area between curves

By integrating the difference of two functions, you can find the area between them.

### Arc length

Integral calculus isn't only useful for finding area. For example, it can also be used to find lengths of one-dimensional curves. Learn all about it here.

### Area defined by polar graphs

We're used to finding the area under curves in the Cartesian plane, but integration can be used to find area defined by polar curves too.

### Arc length of polar graphs

You may already be familiar with finding arc length of graphs that are defined in terms of rectangular coordinates. We'll now extend our knowledge of arc length to include polar graphs.
