(a) Show that if f and g are functions for whichf(x) = g(x) and g(x) = f(x)for all x
Chapter 4, Problem 35(choose chapter or problem)
(a) Show that if f and g are functions for which
\(f^{\prime}(x)=g(x) \text { and } g^{\prime}(x)=-f(x)\)
for all x, then \(f^{2}(x)+g^{2}(x)\) is a constant.
(b) Give an example of functions f and g with this property.
