Best ResponseYou've already chosen the best response.0Simply the numerator is the derivative of the denominator. And hence, the integral I: I=ln Isecx1I+c

Best ResponseYou've already chosen the best response.0Oh, let u=secx1 my bad, otherwise you have two use substitutions. To respond to your last comment, it's not a matter of which secx, you are making a statement saying that ALL secx will now equal another variable called "u".
