WebAug 25, 2015 · Can anyone explain to me how to prove Green's identity by integrating the divergence theorem? I don't understand how divergence, total derivative, and Laplace are related to each other. Why is this true: $$\nabla \cdot (u\nabla v) = u\Delta v + \nabla u \cdot \nabla v?$$ How do we integrate both parts? Thanks for answering.
