" 13."int(sec theta)/(tan^(2)theta)d theta

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

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

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

(tan theta)/(sec theta+1)+(sec theta+1)/(tan theta)=2cos ec theta

int_(0)^((pi)/(2))(sec theta-tan theta)d theta

int(sec^(2)theta d theta)/(tan^(3)theta+4tan theta)

Evaluate int (sec^2 theta)/( sqrt(3 tan^2 theta -1)) d theta

Prove the following identity: (tan theta+sec theta-1)/(tan theta-sec theta+1)=(1+s int n eta)/(cos theta)

(tan theta+sec theta-1)/(tan theta-sec theta+1)

The value of int_(-(pi)/(4))^((pi)/(4))log(sec theta-tan theta)d theta
