WebMar 26, 2016 · To simplify this, use the cosine product-to-sum formula, namely: cos(A)cos(B) = 1 2[cos(A− B) +cos(A +B)] Applying this to the cosine functions in the integral, we see that it becomes = ∫ 1 2 [cos(mx − nx) +cos(mx + nx)]dx We can split up the integral through addition and do a little internal factoring: = 1 2 ∫cos(x(m− n))dx + 1 … WebSo we simply have to show that cos(x),cos(αx) share a period. Note that the periods of cos(x) are 2nπ with n ∈ Z, and the periods of cos(αx) are 2mπ/α, where m ∈ Z. The question is then, do these two sets of numbers share an element, i.e. is there an n and an m so that 2nπ = 2mπ α? If α = p/q, then we have 2nπ = 2mqπ p, or n = mq p. kit clif
