Answers (1)

Answer: $\frac{2 \pi}{5}$

Hint: $\tan ^{-1} x+\cot ^{-1} x=\frac{\pi}{2}$

Given: $\tan ^{-1} x=\frac{\pi}{10}, x \in R$

Solution:

$\cot ^{-1} x=\frac{\pi}{2}-\frac{\pi}{10}$

$\begin{aligned} &=\frac{5 \pi-\pi}{10} \\ &=\frac{4 \pi}{10} \end{aligned}$

$\cot ^{-1} x=\frac{2 \pi}{5}$
