ધારો કે $f:(0,2) \rightarrow R$ એ $f(x) = \log_{2}\left(1+\tan\left(\frac{\pi x}{4}\right)\right)$ તરીકે વ્યાખ્યાયિત છે. તો,$\lim_{n \rightarrow \infty} \frac{2}{n}\left(f\left(\frac{1}{n}\right)+f\left(\frac{2}{n}\right)+\ldots+f(1)\right)$ ની કિંમત શોધો.

$\int_{\pi / 11}^{9 \pi / 22} \frac{d x}{1+\sqrt{\tan x}} = $

$\int_0^{\alpha / 3} \frac{f(x)}{f(x)+f\left(\frac{\alpha-3 x}{3}\right)} d x=$
