If you are familiar with AM-GM inequality, here is a cute solution: Let $a=\log _{\sin(x)\cos(x)}(\sin(x)), b= \log_{\sin(x)\cos(x)}(\cos(x))$. You know $$a+b=1 \\ ab=\frac{1}{4}$$ Therefore, both numbers are positive, and by AM-GM we have $$\frac{1}{2}=\sqrt{1}{4}=\sqrt{ab} \leq \frac{a+b}{2}=\frac{1}{2}$$

2014年12月16日 · The goal is to compute the Fourier series of $g(x)=\log\sin x$ over $[0,\pi]$, or the Fourier series of $h(x)=\log\sin\frac{x}{2}$ over $[0,2\pi]$, or the Fourier series of $f(x)=\log\cos\frac{x}{2}$ over $[-\pi,\pi]$.
