Question:
For \(x\in\mathbb R\), \(\cot^{-1}x=\ \ ?\)
For \(x\in\mathbb R\), \(\cot^{-1}x=\ \ ?\)
Show Hint
$\tan$ and $\cot$ are complementary: swap with $\frac{\pi}{2}-\,$angle.

- \(\dfrac{\pi}{2}-\sin^{-1}x\)
- \(\dfrac{\pi}{2}-\cos^{-1}x\)
- \(\dfrac{\pi}{2}-\tan^{-1}x\)
- \(\dfrac{\pi}{2}-\sec^{-1}x\)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
\(\cot\theta=\tan\!\left(\tfrac{\pi}{2}-\theta\right)\).
Apply inverse on both sides (with principal ranges):
\(\cot^{-1}x=\tfrac{\pi}{2}-\tan^{-1}x\).
