# Integration

Integration is the inverse operation of differentiation.

Let y = f (x) be a function of x. The derivative of y with respect to x is given by

Therefore, the integral of f â€²(x) with respect to x is given by

This type of integration is done without any defined values for the variable x. Hence, it is known as indefinite integration. We need to add a constant of integration â€˜câ€™ to the final result in case of indefinite integration.
