Numerical Value of a Definite Integral

Antiderivative: An antiderivative is an indefinite integral that "undoes" differentiation. It helps find functions whose derivatives match a given function.

Riemann Sum: A method for approximating the area under a curve using rectangles. By increasing the number of rectangles, we can get closer to the exact value represented by the definite integral.

Fundamental Theorem of Calculus: This theorem establishes a connection between differentiation and integration. It states that if F(x) is an antiderivative of f(x), then ∫[a to b] f(x) dx = F(b) - F(a).
