સંકલન $\frac{48}{\pi^{4}} \int_{0}^{\pi} \left(\frac{3 \pi x^{2}}{2} - x^{3}\right) \frac{\sin x}{1 + \cos^{2} x} dx$ નું મૂલ્ય કેટલું થાય?

$\int_{ - \pi /2}^{\pi /2} {\log \left( {\frac{{2 - \sin \theta }}{{2 + \sin \theta }}} \right)\,d\theta = } $

ધારો કે $f(x)$ એ $(a, b)$ પર સંકલનીય છે,જ્યાં $b > a > 0$. જો $I_1 = \int_{\frac{\pi}{6}}^{\frac{\pi}{3}} f(\tan \theta + \cot \theta) \sec^2 \theta \, d\theta$ અને $I_2 = \int_{\frac{\pi}{6}}^{\frac{\pi}{3}} f(\tan \theta + \cot \theta) \csc^2 \theta \, d\theta$ હોય,તો ગુણોત્તર $\frac{I_1}{I_2}$ શું છે?

$\int_{-1}^1 \sin^5 x \cos^4 x \, dx$ ની કિંમત શું છે?

ધારો કે $f(x) = \frac{\sin x}{x}$,તો $\int_{0}^{\frac{\pi}{2}} f(x) f\left(\frac{\pi}{2} - x\right) dx =$
