WebJun 7, 2024 · Use Green’s Theorem in the form of Equation 13 to prove Green’s first identity: where D and C satisfy the hypotheses of Green’s Theorem and the appropriate partial derivatives of f and g exist and are continuous. (The quantity ∇g • n = D n g occurs in the line integral. WebTranscribed image text: Recall from a previous section that a function g is called harmonic on D if it satisfies Laplace's equation, that is, V^2g = 0 on D. Use Green's first identity (with the same hypothesis as in this exercise) to show that if g is harmonic on D, then integral D_ng ds = 0. Here D_ng is the normal derivative of g defined in this exercise.
