Question

principle value of sin inverseundr root three/two

Answer 1

sin60=√3/2
reverse for the cosec 60
cosec60=2√3
may be the answer

Answer 2

Hey there!

Solution:


$sin^{-1}(\frac{\sqrt{3}}{2})\\ \\ Let \:y\: = sin^{-1}\:(\frac{\sqrt{3}}{2})\\ \\ \bf{Therefore}, \\ \\ sin\:y = \frac{\sqrt{3}}{2} \\ \\ We\: know\: that \frac{\sqrt{3}}{2} lies\: at\: sin\:(\frac{\pi}{3})\\ \\ sin\:y = sin\:(\frac{\pi}{3})\\ \\\bf{sin \:y\: and \:sin \:cancelled\: out} \\ \\ \bf{So \:we \:get:}\\ \\ y = \frac{\pi}{3}$
