Prove the following: sqrt(frac(1+sin2x)(1-sin2x))=tan(pi/4+x)

If y =sqrt((1-sin2x)/(1+sin2x)) then ((dy)/(dx))_(x = 0) =

int((sqrt(2sin2x+4cos^(2)x+sin4x)-2x)/(1+sin2x))dx

int_(0)^( pi//2)sqrt((1-sin2x)/(1+sin2x))dx

find dy/dx , (sqrt((1-sin2x)/(1+sin2x))) is equal to, 0ltxltpi/2

int(2sin x)/((3+sin2x))dx is equal to (1)/(2)ln|(2+sin x-cos x)/(2-sin x+cos x)|-(1)/(sqrt(2))tan^(-1)((sin x+cos x)/(sqrt(2)))+c(1)/(2)ln|(2+sin x-cos x)/(2-sin x+cos x)|-(1)/(2sqrt(2))tan^(-1)((sin x+cos x)/(sqrt(2)))+c(1)/(4)ln|(2+sin x-cos x)/(2-sin x+cos x)|-(1)/(sqrt(2))tan^(-1)((sin x+cos x)/(sqrt(2)))+cnone of these

Evaluate: int sqrt((1-sin2x)/(1+sin2x))dx

int sqrt(1-sin2x)
