વિધેયનું સંકલન કરો: $\frac{e^{x}}{(1+e^{x})(2+e^{x})}$

જો $\int \frac{2x^2+3}{(x^2-1)(x^2-4)} dx = \log \left[\left(\frac{x-2}{x+2}\right)^a \cdot \left(\frac{x+1}{x-1}\right)^b\right] + c$,(જ્યાં $c$ એ સંકલનનો અચળાંક છે),તો $a+b$ ની કિંમત શોધો.

જો $\int \frac{d x}{(x+2)\left(x^2+1\right)}=a \log \left|1+x^2\right|+b \tan ^{-1} x+\frac{1}{5} \log |x+2|+c$ હોય,તો

જો $\int \frac{2x+3}{(x-1)(x^2+1)} dx = \log_e {(x-1)^{\frac{5}{2}}(x^2+1)^a} - \frac{1}{2} \tan^{-1} x + A$ જ્યાં $A$ એક સ્વૈચ્છિક અચળાંક છે,તો $a$ ની કિંમત શોધો.
