WebIn mathematics, Green's identities are a set of three identities in vector calculus relating the bulk with the boundary of a region on which differential operators act. They are named after the mathematician George Green, who discovered Green's theorem. Part of a series of articles about Calculus Fundamental theorem Limits Continuity WebProve Green’s first identity: For every pair of functions f(x), g(x) on (a;b), b a f00(x)g(x)dx = b a f0(x)g0(x)dx+f0g b: Solution To solve this problem, one should use integration by parts. The formula for it is b a udv = uv b a vdu: Starting from b a f00(x)g(x)dx; let u = g(x) dv = f00(x)dx du = g0(x)dx v = f0(x): Then we have b a f00(x)g(x ...
