સંકલન $\int \frac{x^2 + \cos^2 x}{1 + x^2} \operatorname{cosec}^2 x \, dx$ ની કિંમત શોધો,જ્યાં $c$ એ સંકલનનો અચળાંક છે.

જો $\int \frac{2 \, dx}{\sqrt{\cot^2 x - \tan^2 x}} = -\sqrt{f(x)} + c$ હોય, તો $f(x) =$

ધારો કે $\beta(m, n) = \int_0^1 x^{m-1}(1-x)^{n-1} dx$,જ્યાં $m, n > 0$. જો $\int_0^1 (1-x^{10})^{20} dx = a \times \beta(b, c)$ હોય,તો $100(a+b+c)$ ની કિંમત શોધો:
