$\int \frac{1+x^{2}}{\left(1-x^{2}\right)\left(1+x+x^{2}\right)} d x=A \log (1+x)+B \log \left(1-x^{3}\right) .$ Then $A+3 B$ is (a) 0 (b) 1 (c) $-1$ (d) 2
The value of the integral $\int \frac{\log (x+1)-\log x}{x(x+1)} d x$ is (a) $-(1 / 2)(\log x+1)^{2}-(1 / 2)(\log x)^{2}+$ $\log (x+1) \log x+C$ (b) $-\left[\left(\log (x+1)^{2}-(\log x)^{2}\right]\right.$ $+\log (x+1) \log x+C$ (c) $C-(1 / 2)\left(\log (1+1 / x)^{2}\right.$ (d) none of these
$\int_{0}^{1}\left(\frac{2-x}{1+x}\right) d x$ is (a) $3 \log 2$ (b) $2 \log 2-1$ (c) $3 \log 2+1$ (d) $3 \log 2-1$
