Chapter 14.1, Problem 56SR

To determine

To find:Value of ${\sin }^{-1}\left(\frac{\pi }{2}\right)$

Answer to Problem 56SR

Undefined

Explanation of Solution

Given information:

We know that, the given expression is ${\sin }^{-1}\left(\frac{\pi }{2}\right)$

Calculation :

  $\begin{array}{l}\Rightarrow {\sin }^{-1}\left(\frac{\pi }{2}\right)\\ \Rightarrow {\sin }^{-1}\left(\frac{3.14}{2}\right)\\ \Rightarrow si{n}^{-1}(1.57)\\ \Rightarrow si{n}^{-1}(>1)\end{array}$

  $\Rightarrow$ Argument of ${\text{sin}}^{-1}x$ should not be greater than 1

  $\therefore$ = Undefined
