Show that the function sin(3x) and sin(4x) are orthonormal basis functions
Added by James F.
Step 1
∫_0^π sin(3x)sin(4x) dx = (1/2)∫_0^π cos(x)dx - (1/2)∫_0^π cos(7x)dx = 0 Therefore, sin(3x) and sin(4x) are orthogonal. Show more…

Let {en}n∈ℕ be an orthonormal basis for a Hilbert space H, and let {fn}n∈ℕ be an orthonormal set in H such that ∑_{n∈ℕ} ||en - fn||^2 < 1. Prove that {fn}n∈ℕ is an orthonormal basis for H.
