$y=\int \cos \left\{2 \tan ^{-1} \sqrt{\frac{1-x}{1+x}}\right\} d x$ એ કોનું સમીકરણ છે?

ધારો કે $x > 0$ એ એક નિશ્ચિત વાસ્તવિક સંખ્યા છે. તો,સંકલન $\int \limits_0^{\infty} e^{-t}|x-t| d t$ ની કિંમત શોધો.

જો $\int \frac{dx}{\cos^3 x \sqrt{2 \sin 2x}} = (\tan x)^A + C(\tan x)^B + K$,જ્યાં $K$ એ સંકલનનો અચળાંક છે,તો $5(A+B+C)$ ની કિંમત શોધો.
