Nov 14, 2017 · Prove that an integral $$\int_0^{\pi/2} \cos^{10}x\cdot \cos(12x)\,\text{d}x=0$$ I'm sorry but I am completely lost.

Apr 12, 2015 · For an odd function, I know that f(x) = - f(x). I'm trying to show that $\int^{a}_{-a} f(x) dx$ = 0. I've seen the proof where it splits the integral up into: $$\int^{a}_{0} f(x) dx + …
