The Fundamental Theorem of Calculus bridges differentiation and integration, two core concepts in calculus. It consists of two parts: the first establishes that the derivative of an integral function is the original function, while the second allows for the evaluation of definite integrals using antiderivatives. This theorem is crucial for calculating areas, volumes, and other quantities in various fields.
