Find the value of $ tan^{-1}\sqrt{3} - cot^{-1}\sqrt{3} $.

Sept. 24, 2023
Solution:
We know:-
$ tan^{-1}\sqrt{3} = \frac{\pi}{3}$
$cot^{-1}\sqrt{3} = \frac{\pi}{6}$
$ tan^{-1}\sqrt{3} - cot^{-1}\sqrt{3} $ = $ \frac{\pi}{3} - \frac{\pi}{6} = \frac{2\pi - \pi}{6} = \frac{\pi}{6} $
So, $ tan^{-1}\sqrt{3} - cot^{-1}\sqrt{3} = \frac{\pi}{6}$
