11the answer should be 0...
as right hand side can give a minimum of 3 if sin3x=0...
whereas the left side has a maximum of 3, if sinx=1 and sin2x=1.... as the sine of any angle can not exceed 1..
therefore, the above relation to hold true...
sinx = sin2x = sin3x =1 must also hold... which is never true...
