" ta."int(sec theta)/(lan^(2)theta)d theta

int(sec theta)/(tan^(2)theta)d theta is.

int(sqrt(cos2 theta))/(sin theta)d theta=

int(sec theta)/(sec theta-tan theta)d theta

int(sectheta)/(sec theta+tantheta)d theta=

int(d theta)/(sin theta+sin2 theta)

Evaluate: int_(-pi)^(3 pi)log(sec theta-tan theta)d theta

int e^(tan theta)(sec theta-sin theta)d theta is equal to: (A)-e^(tan theta)sin theta+c(B)e^(tan theta)sin theta+c(C)-e^(tan theta)sec theta+c(D)e^(tan theta)cos theta+c

Prove that : (sec theta-tan theta)/(sec theta+tan theta)= 1-2 sec theta tan theta+ 2 tan^2 theta .

(tan theta)/(sec theta-1)+(tan theta)/(sec theta+1) is equal to 2tan theta(b)2sec theta(c)2cos ec theta(d)2tan theta sec theta
