Question:
Evaluate using integration by parts:
{eq}\displaystyle \int \tan^{-1} x\ dx {/eq}.
Indefinite Integral:
The formula of integration that we have used in the given problem are: {eq}\int \frac{x}{x^2+1}dx=\frac{1}{2}\ln \left|x^2+1\right|+c\\ \int \frac{1}{u}du=\ln \left(\left|u\right|\right)+c\\ \int adx=ax+c\\ {/eq} Similarly, the rule that we have used are: {eq}\int \:uv'=uv-\int \:u'v\\ \int \:f\left(g\left(x\right)\right)\cdot \:g'\left(x\right)dx=\int \:f\left(u\right)du,\:\quad \:u=g\left(x\right) {/eq}
