An '''indefinite integral''', or antiderivative, is an [[integral]] without upper and lower limits.
An '''indefinite integral''', or antiderivative, is an [[integral]] without upper and lower limits.
−
There is an infinite number of antiderivatives for a given function, because each indefinite [[integral]] can have an arbitrary constant added to it which disappears upon integration. However, the [[fundamental theorem of calculus]] relates a [[definite integral]] to an indefinite integral by taking its value at the boundary points.
