Answered by Frix last updated on 08/Sep/23

$$\int \frac{dx}{\sqrt{{\cos }^{3}x{\sin }^{5}x}}\stackrel{t=\tan x}{=}$$$$\int (t^{-\frac{1}{2}}+t^{-\frac{5}{2}})dt=2t^{\frac{1}{2}}-\frac{2}{3}{t}^{-\frac{3}{2}}=\frac{2(3t^2-1)}{3t^{\frac{3}{2}}}=$$$$=-\frac{2(1-2\sin x)(1+2\sin x)}{3\sqrt{\cos x{\sin }^{3}x}}+C$$$$\mathrm{The}\mathrm{integral}\mathrm{does}\mathrm{not}\mathrm{converge}\mathrm{for}x\in [\frac{\pi }{4},\frac{\pi }{2}]$$
