### Integration - Area under a graph

Integration can be used to find the area bounded by a curve y = f(x), the x-axis and the lines x=a and x=b by using the following method.

However, you must be very careful in the way you use this as the following examples will show.

In this tutorial I show you how to find the area bounded by a curve when it is above the x-axis.
