સંકલન $\int_3^6 \frac{\sqrt{x}}{\sqrt{9-x}+\sqrt{x}} d x$ ની કિંમત શોધો.

$\int_0^1 \frac{\log _e(1+x)}{1+x^2} d x=$

$\int_0^{\frac{\pi}{4}} \frac{\cos ^2 x}{\cos ^2 x+4 \sin ^2 x} d x=$

$\int_0^1 x(1-x)^n dx =$

$\int\limits_0^{\pi / 2n} \frac{dx}{1 + \tan^n(nx)} = $

$n \in N$ માટે,જો $I_n = \int \frac{\sin nx}{\sin x} dx = \frac{2}{n-1} \sin(n-1)x + I_{n-2}$ અને $\int_0^\pi \frac{\sin nx}{\sin x} dx = \frac{k\pi}{2}$ હોય,તો $k =$
