+A contour integral is an integral of a [Complex Function](/wiki/complex_function) along a specified [Contour](/wiki/contour) (a path) in the complex plane. This powerful tool in [Complex Analysis](/wiki/complex_analysis) uncovers deep properties of functions and elegantly simplifies the evaluation of certain real integrals.
