## Integration

Integration is vital in engineering. It is the key mathematical tool for finding the centre of mass or the surface area of a body.

Integration is also called antidifferentiation. It is the reverse process of differentiation. If you differentiate an expression, you can integrate it to get back to the original. Geometrically, differentiation provides the slope of graph, whereas integration yields the area below.

These integration worksheets will help you to improve your skills in these areas.
