$\int {{e^x}(1 - \cot x + {{\cot }^2}x)\,dx} $ ની કિંમત શોધો.

જો $\int e^x\left(\frac{x \sin ^{-1} x}{\sqrt{1-x^2}}+\frac{\sin ^{-1} x}{\left(1-x^2\right)^{3 / 2}}+\frac{x}{1-x^2}\right) d x=g(x)+C$ જ્યાં $C$ એ સંકલનનો અચળાંક છે,તો $g \left(\frac{1}{2}\right)$ ની કિંમત શોધો :

$\int \frac{(x^{2}+1) e^{x}}{(x+1)^{2}} d x=f(x) e^{x}+C$,જ્યાં $C$ અચળ છે,તો $x = 1$ આગળ $\frac{d^{3} f}{d x^{3}}$ ની કિંમત શોધો.

$\int \left( \frac{2 - \sin 2x}{1 - \cos 2x} \right) e^x \, dx$ ની કિંમત શોધો.

ધારો કે $f(x) = \frac{2\sin^2 x - 1}{\cos x} + \frac{\cos x(2\sin x + 1)}{1 + \sin x}$ છે,તો $\int e^x(f(x) + f'(x)) dx$ શોધો (જ્યાં $c$ એ સંકલનનો અચળાંક છે).
