@ash2326 domain of sin(x) is (R), while its range is [1,1]

Good, to have the inverse of sin function, we limit it's range domain= range of sin x= [1, 1] Range = \(\large [\frac{\pi}{2}, \frac{\pi}{2}]\) DO you get this?

if x is positive, then y lies in \([0, \frac {\pi}{2}]\) if x is negative, then y lies in \([\frac{\pi}{2}, 0)\) Now what's \(\sin^{1}(\frac{\sqrt 3}{2})\) ?

Sorry, I was away. But sin (45) is not \(\frac{\sqrt 3}{2}\) it's, \(\frac{1}{\sqrt 2}\).
