Antiderivative

An antiderivative is a function that reverses differentiation. In simple terms, if you know how a function changes at every point (its derivative), an antiderivative helps you find the original function that had that rate of change. It's like retracing steps to discover the initial path traveled, based on how movement occurs along the way. Antiderivatives are fundamental in calculus for solving problems involving areas, accumulated quantities, or restoring original functions from their rates of change.
