\[\ln (\left cosx \right)+C\]or\[\ln (\left secx \right)+C\]You just have to memorize trig integrals like this, or you may also be able to find it by using integration by parts.

Actually I just realized with this one you do this:\[\int\limits_{}^{}(tanx) dx\]\[\int\limits_{}^{}(sinx/cosx)dx\]\[\int\limits_{}^{}(sinx/cosx)dx\]Now use substitution where u=cosx and du=sinx \[\int\limits_{}^{}(1/u)du\]\[\ln \left u \right+C\]\[\ln \left cosx \right+C\]
