1. A function whose derivative is a given function; the inverse operation of differentiation in calculus.
Usage: mathematics; also called an indefinite integral

Examples

• The antiderivative of 2x is x² plus a constant.
• Finding the antiderivative is a key skill in integral calculus.
• If f(x) = 3x², then an antiderivative is x³.
• The antiderivative of a constant function is a linear function.
• Students learn to find antiderivatives using integration techniques.
• The antiderivative is not unique; it differs by a constant of integration.
