WebUse Green’s first identity to prove Theorem 3. (Hint: Substitute f(x) = X(x) = g(x), a real eigenfunction.) Solution Theorem 3 reads as follows: Assume the same conditions as in Theorem 1. If f(x)f0(x) x =b x=a 0 (10) for all (real-valued) functions f(x) satisfying the BCs, then there is no negative eigenvalue. 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. real analysis book with solutions
