In mathematics, a surface integral is a definite integral taken over a surface (which may be a curve set in space); it can be thought of as the double integral analog of the line integral. Given a surface, one may integrate over its scalar fields (that is, functions which return numbers as values), and vector fields (that is, functions which return vectors as values).
