જો $\int {\frac{{\csc^2 x}}{{{{\left( {\csc x + \cot x} \right)}^{\frac{9}{2}}}}}\,dx} = {\left( {\csc x - \cot x} \right)^{\frac{7}{2}}}\left( {\frac{1}{\alpha } + \frac{{{{\left( {\csc x - \cot x} \right)}^2}}}{{11}}} \right) + C$ (જ્યાં $C$ એ સંકલનનો અચળાંક છે અને $\alpha \in N$),તો $\alpha$ ની કિંમત શોધો.

ધારો કે $f(x)=7 \tan^8 x + 7 \tan^6 x - 3 \tan^4 x - 3 \tan^2 x$ માટે,$I_1 = \int_0^{\pi/4} f(x) \, dx$ અને $I_2 = \int_0^{\pi/4} x f(x) \, dx$ છે. તો $7 I_1 + 12 I_2$ ની કિંમત શોધો:

$\int \frac{1}{x^5 \sqrt[5]{x^5+1}} d x=$

$\int \frac{2 \cos 2 x}{(1+\sin 2 x)(1+\cos 2 x)} d x=$
