9. int_0^(pi/2)sec^4theta d theta

5. int_0^(pi/4)sec^2theta d theta

The value of int_(0)^((pi)/(4))sectheta(sectheta-tantheta)d theta is-

The value of int_(-pi)^(3pi)log(sectheta-tantheta)d""theta is

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

The value of int_(-pi/4)^(pi/4) log(sectheta-tantheta)d theta is

The value of int_(-pi/4)^(pi/4) log(sectheta-tantheta)d theta is

int_0^(pi//2)(theta/sintheta)^2d theta=

If int_0^(pi/2)logsinthetad theta=k , then find the value of int_0^(pi/2)(theta/(sintheta))^2d theta in terms of k
