sqrt(cos 2x) + sqrt(1 + sin 2x) = 2sqrt(sin x + cos x) if

int sqrt(1-sin2x)

show that , cot ^(-1) {(sqrt(1+sin x)+sqrt(1- sin x))/( sqrt(1+sin x)- sqrt(1-sin x))}=(x)/(2),0 lt x lt (pi)/(2)

Evaluate: int sqrt(1+cos2x) dx (ii) int sqrt(1+sin2x) dx.

Evaluate: (i) sqrt(1-cos2x)dx (ii) int sqrt(1+sin2x)dx
