Antiderivatives

Definition of Antiderivatives
If F is an antiderivative of f on an interval I, then G is an antiderivative of f on the interval I if and only if G is of the form G(x) = F(x) + C,       for all x in I where C is a constant.

Note that to find the antiderivative of a function, one must integrate. Also the antiderivate is also called the indefinite integral.
