Squaring on both sides,you get sin2x + 2sinxcosx + cos2x = 1
which gives 1 + 2sinxcosx = 1 {since sin2x +cos2x = 1 for all x}
which means,2sinxcosx =0
which means either sinx =0 or cosx=0
so,the general solution is that for sinx=0 union cosx=0

Sin x + cos x = 1 squaring both sides sin^2 x + cos^2 x +2sinx cosx = 1 1+ 2sin x cos x = 1 2 sin x cos x =0 where( 2 sin x cos x = sin 2 x ) implies sin 2x = 0.
