0

$- \frac{π}{4}$

$- \frac{π}{2}$

$\frac{π}{2}$

$- \frac{π}{2}$

$\int_{- 1}^{1} \frac{d}{dx} (\tan^{- 1} (\frac{1}{x})) d x = \int_{- 1}^{1} (\frac{d}{dx} \cot^{- 1} (x)) d x = \int_{- 1}^{1} \frac{- 1}{{(1 + x)}^{2}} d x = - 2 \int_{0}^{1} \frac{1}{{(1 + x)}^{2}} d x = - 2 {[\tan^{- 1} (x)]}_{0}^{1} = - 2 \times \frac{π}{4} = - \frac{π}{2}$
