Let f : R → R be an odd differentiable function. Define F: R2 → R by F(x, y) = f(x² + xy+9y²). (a) Differentiating F with respect to x gives ƏF = g(x,y) f' (x² + xy+ 9y²) dx where g(x, y) (b) F satisfies the partial differential equation OF g(x, y) – h(x, y) dy - where h(x, y) (c) You are given that F(x, -x) = –7x2 for all x E R. Now we can find the rule for f to be f(t) = Finally, the rule for F becomes F(x, y)
