Surface area by integration
WebThere are many ways to extend the idea of integration to multiple dimensions: some examples include Line integrals, double integrals, triple integrals, and surface integrals. Each one lets you add infinitely many infinitely small values, where those values might come from points on a curve, points in an area, or points on a surface. These are all very powerful … Web2.
