$\int_{-1}^3\left(\cot ^{-1}\left(\frac{x}{x^2+1}\right)+\cot ^{-1}\left(\frac{x^2+1}{x}\right)\right) d x=$

ધારો કે $m, n, p, q$ ચાર ધન પૂર્ણાંકો છે. જો $\int_0^{2 \pi} \sin^m x \cos^n x \, dx = 4 \int_0^{\pi/2} \sin^m x \cos^n x \, dx$, $\int_0^{2 \pi} \sin^p x \cos^n x \, dx = 0$, $\int_0^{\pi} \sin^p x \cos^q x \, dx = 0$, $a = m + n + p$ અને $b = m + n + q$ હોય, તો:

નિશ્ચિત સંકલનનું મૂલ્ય શોધો: $\int_{\pi / 4}^{\pi / 2} \frac{3 \, dx}{1+e^{\sqrt{8} \sin \left(x-\frac{3 \pi}{8}\right)}}$

$\int_{-\pi/2}^{\pi/2} \frac{\sin^2 x}{1 + 2^x} dx = \dots$

$\int_{-1/2}^{1/2} (\cos x) \left[ \log \left( \frac{1-x}{1+x} \right) \right] dx = $

$\int\limits_{\frac{-\pi}{2}}^{\frac{\pi}{2}} \frac{\sin^2 x}{1 + (2017)^x} \, dx$ નું મૂલ્ય શોધો.
