An antiderivative of a function $f(x)$ is another function $F(x)$ such that the derivative of $F(x)$ is equal to $f(x)$. It is also known as the indefinite integral of $f(x)$.
Definite Integral: The definite integral of a function over an interval [a, b] represents the signed area under the curve from a to b.
Fundamental Theorem of Calculus: This theorem links differentiation and integration, stating that differentiation and integration are inverse processes.
Integration by Parts: A technique used to integrate products of functions based on the product rule for differentiation.
