|dw:1351091765743:dw|notice that \[\frac{ \sqrt{2} }{ 2 }=\frac{ 1 }{ \sqrt{2} }\]
which we remember from the triangle

simple \[\sqrt{2}/2=1/\sqrt{2}\]
it will affect only if the value is out of range

sin x is basicaly defined for all values of x but -1<sin x<1 happens always when we define sin^-1 x it is a inverse or we can say just opposite to the sinx which is defined for -1<x<1 and answer lies anywhere so a basic principle regien is defined and all other area is called general area so we knoww that sin 45 = 1/\[\sqrt{2}\] so sin -1 x = 45 degree or pi/4 radians in principal region.............k
