Integration

Integration is the mathematical operation of finding the area between a graph and the axis of the dependent variable over a given interval. Integration is the opposite of differentiation (an integral is often called an antiderivative).
==Multivariable extensions==
A line integral is an integral taken over a curve above a plane, and a surface integral is one taken over a surface in three dimensions. Both can be taken over scalar, vector, or tensor fields.
