```							1- 2 sin^2 X - sinx +5=0.   (We know that cos2x= 1-2sin^2x)2sin^2 x+sinx -6=0(2sinx-3)(sinx+2)=0We got two value of sinx= 3/2, -2From second equation 4cos^2 X - 4cosx +1 =0. (we know that secx = 1/cosx(2cox-1)^2=0We got cosx= ½It means these two equations does not cross each other at any pointThanks and keep asking if any doubt
