The word "surface" is an important term in mathematics and is used in many ways. To find an explicit formula for the surface integral over a surface S, we need to parameterize S by defining a system of curvilinear coordinates on S, like the latitude and longitude on a sphere.Let such a parameterization be x(s, t), where (s, t) varies in some region T in the plane.Then, the surface integral is given by Calculus: Integral with adjustable bounds.

I don't know however how to check my solution using computer programs when evaluating surface integrals over scalar or vector fields. Volume and Surface Integrals Used in Physics. The most common and straightforward use of the word is to denote a two-dimensional submanifold of three-dimensional Euclidean space.Surfaces can range from the very complicated (e.g., fractals such as the Mandelbrot set) to the very simple (such as the plane). Recall that in line integrals the orientation of the curve we were integrating along could change the answer.
