Question: The general value of \({\cos h}^{- 1}x\) is....

The general value of cos⁡h−1x{\cos h}^{- 1}x is.

A

2πri+log⁡(x+x2+1)2\pi ri + \log(x + \sqrt{x^{2} + 1})

B

2πri+log⁡(x+x2−1)2\pi ri + \log(x + \sqrt{x^{2} - 1})

C

πri+(−1)rlog⁡(x+x2+1)\pi ri + ( - 1)^{r}\log(x + \sqrt{x^{2} + 1})

D

2πri+(−1)rlog⁡(x+x2−1)2\pi ri + ( - 1)^{r}\log(x + \sqrt{x^{2} - 1})

Answer

2πri+log⁡(x+x2−1)2\pi ri + \log(x + \sqrt{x^{2} - 1})
