Question: If cos<sup>–1</sup> \(\left( \frac { 1 } { x } \right)\) = q, then tan q =...

If cos–1 (1x)\left( \frac { 1 } { x } \right) = q, then tan q =

A

1x2−1\frac { 1 } { \sqrt { \mathrm { x } ^ { 2 } - 1 } }

B

x2+1\sqrt { \mathrm { x } ^ { 2 } + 1 }

C

D

x2−1\sqrt { \mathrm { x } ^ { 2 } - 1 }

Answer

x2−1\sqrt { \mathrm { x } ^ { 2 } - 1 }

Explanation

Solution

Given that cos–1 = q Ž cos q =

Now, tan q = x2−1\sqrt { \mathrm { x } ^ { 2 } - 1 }
