int(cos x-sin x)/(1+sin2x)dx

int (cos x - sin x)/(1 + sin 2x) dx

int(cos x+sin x)/(cos x-sin x)(1-sin2x)dx

int(cos x-sin x)/(sqrt(sin2x))dx

(i) int (cos x-sin x)/sqrt(1+ sin 2x) dx (ii) int (cos x) /((cos (x/2)+sin (x/2))) dx

int (cos x - sin x)/ (1+2 sin x cos x ) dx is equal to a) - 1/(cos x- sin x)+c b) (cos x + sin x)/(cos x- sin x)+c c) - 1/(cos x+ sin x)+c d) x_1/(sin x+ cos x)+c

Evaluate: int(cos x-sin x)/(cos x+sin x)(2+2sin2x)dx

int(2cos x)/((1-sin x)(1+sin^(2)x))dx

int(cos x-sin x)/(sqrt(8-sin2x))dx=sin^(-1)((sin x+cos x)/(a))+c
