Integration is a mathematical process that finds the area under a curve or the accumulation of quantities. It can also be used to find the original function from its rate of change (its derivative).

Explanation: The notation \$ ∫f(x)dx \$ denotes the integration of a function, where f(x) is the integrand and dx is the variable of integration. The antiderivative or indefinite integral of f(x) is represented by F(x), which is unique to an additive constant C.
