$$\underset{0}{\stackrel{\frac{1}{2}}{\int }}{\left(\tan \pi x\right)}^{\frac{4}{5}}dx\stackrel{t={\left(\cot x\right)}^{\frac{1}{5}}}{=}$$$$=-\frac{5}{\pi }\underset{\mathrm{\infty }}{\stackrel{0}{\int }}\frac{dt}{t^{10}+1}=\frac{5}{\pi }\underset{0}{\stackrel{\mathrm{\infty }}{\int }}\frac{dt}{t^{10}+1}=\frac{1+\sqrt{5}}{2}$$
