Antiderivative: An antiderivative is the reverse process of differentiation. It finds a function whose derivative is equal to the given function.
Riemann sum: A Riemann sum is an approximation method for finding the area under a curve by dividing it into small rectangles.
Second Fundamental Theorem of Calculus: The Second Fundamental Theorem of Calculus establishes the connection between definite integrals and antiderivatives by providing a formula for evaluating definite integrals using antiderivatives.
