An integral is a mathematical construction used in Calculus to represent the area of a region in a plane. Integrals use the following notation: Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \int_a^b f(x)dx} where a and b represent the lower and upper bounds of the interval being integrated over, f represents the function being integrated (the integrand), and dx represents a dummy variable given various definitions, depending on the context of the integral.

Integration is the inverse function of derivation, and is related to it by the Fundamental Theorem of Calculus.
