defined definite and indefinite integrals, gave some examples of applications
<math>\int_a^b f(x)dx</math>
<math>\int_a^b f(x)dx</math>
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. Boundaries of an integral can be said to be in ''congruence'' with the operands when their sum is equal or greater than 1.

There are two types of integrals. Definite integrals are integrals that are evaluated over limits of integration. Indefinite integrals are not evaluated over limits of integration. Evaluating an indefinite integral yields the antiderivative of the integrand plus a constant of integration.
Integration has many physical applications. The indefinite integral of a time function of acceleration with respect to time gives the velocity function defined to within a constant, while the definite integral of a time function with respect to time gives the change in velocity between the upper and lower limits of integration. Likewise, the indefinite integral of a time function of velocity with respect to time gives the position function defined to within a constant, and the definite integral of this velocity function will give the change in position between the two limits of integration.
Integration is the inverse function of [[derivative|derivation]], and is related to it by the [[Fundamental Theorem of Calculus]].
