int(sec theta)/(tan^(2)*theta)d theta

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

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

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

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

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

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

Prove that (tan theta)/(sec theta-1)+(tan theta)/(sec theta+1)=2 "cosec"theta.

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