a. Suppose that g is an even function of x and h is an odd function of x. Show that if g(x) + h(x) = 0 for all x then g(x) = 0 for all x and h(x) = 0 for all x. b. Use the result in part (a) to show that if f(x) = fE(x) + fo(x) is the sum of an even function fe(x) and an odd function fo(x), then fE(x) = (f(x) + f(-x))/2 and fo(x) = (f(x) – f(-x))/2. c. What is the significance of the result in part (b)?

Question
a. Suppose that g is an even function of x and h is an odd
function of x. Show that if g(x) + h(x) = 0 for all x then
g(x) = 0 for all x and h(x) = 0 for all x.
b. Use the result in part (a) to show that if f(x) =
fE(x) + fo(x) is the sum of an even function fe(x) and an
odd function fo(x), then
fE(x) = (f(x) + f(-x))/2 and fo(x) =
(f(x) – f(-x))/2.
c. What is the significance of the result in part (b)?
