જો $\int \frac{2 x^{2}+3}{\left(x^{2}-1\right)\left(x^{2}+4\right)} d x=a \log \left|\frac{x-1}{x+1}\right|+b \tan ^{-1}\left(\frac{x}{2}\right)+C$ હોય,તો

જો $\int \frac{dx}{x^4+5x^2+4} = A \tan^{-1} x + B \tan^{-1} \frac{x}{2} + c$,જ્યાં $c$ એ સંકલનનો અચળાંક છે,તો:

$\int \frac{dx}{(x^2+1)(x^2+4)} = $

જો $\int \frac{2 x^2-3}{\left(x^2-4\right)\left(x^2+1\right)} d x=A \tan^{-1} x+B \log (x-2)+C \log (x+2)$ હોય,તો $6 A+7 B-5 C=$
