Dear Student,
:- For this question
         At first assume , Sin A= ax,
         So, Cos A= √1-a^2x^2
         Putting the  values in the given question we get ,
         Y= Sin^-1 [ 2 Sin A Cos A]
           = Sin^-1 [ Sin 2A]
           = 2A
       A= Sin^-1 ax
      So, y = 2 Sin^-1 ax.
Cheers!!
