Surface integral of a vector field
WebSurface integrals are used anytime you get the sensation of wanting to add a bunch of values associated with points on a surface. This is the two-dimensional analog of line integrals. Alternatively, you can view it as a … WebA vector field in ℝ2 can be represented in either of two equivalent ways. The first way is to use a vector with components that are two-variable functions: F(x, y) = 〈P(x, y), Q(x, y)〉. (6.1) The second way is to use the standard unit vectors: F(x, y) = P(x, y)i + Q(x, y)j. (6.2)
