Answer:
Write 1 = sin^2 x + cos^2 x (Identity)
And write sin2x = 2sinx cosx
So 1 + sin2x = sin^2 x + cos^2 x + 2sinx cosx
=> Square root of 1 + sin2x = Square root of (sin^2 x + cos^2 x + 2sinx cosx)
= (sinx + cosx) or (-sinx -cosx)
So integral of sinx + cos x dx = -cosx + sinx + c
and integral of -sinx - cos x dx = cosx - sinx + c
