An Orthonormal Basis for a Function Space

Consider the space of functions of the form

Let's create an orthonormal basis for this space.

(a) First, demonstrate that the functions sin nθ form an orthonormal set; that is, prove that

(b) Next, find constants An such that if we define basis functions en = An sin() then
