उत्तर

\[\text{ Here, y }= se c^{- 1} \left( \frac{x + 1}{x - 1} \right) + \sin^{- 1} \left( \frac{x - 1}{x + 1} \right)\]

\[ \Rightarrow y = \cos^{- 1} \left( \frac{x - 1}{x + 1} \right) + \sin^{- 1} \left( \frac{x - 1}{x + 1} \right) ..........\left[ \text{ Since,} se c^{- 1} \left( x \right) = \cos^{- 1} \left( \frac{1}{x} \right) \right]\]

\[ \Rightarrow y = \frac{\pi}{2} ..........\left[ \text{ Since}, \cos^{- 1} \alpha + \sin^{- 1} \alpha = \frac{\pi}{2} \right]\]

Differentiate it with respect to x,

\[\therefore \frac{d y}{d x} = 0\]
