    maybe(guess) simplify the denm by expressing cos2x in terms of cosx then you have cos^2(x) in the denominator. Then divide the numerator then you shpuld get something like ..............................se c^2(x)+2tanx. So just integrate that

    What I love about integral problems is the numerous ways you can solve them... I had a list of >100 integration problems, really great ones, e.g.

    \int \frac{arccos \sqrt{x} - arcsin \sqrt{x} }{arccos \sqrt{x} + arcsin \sqrt{x}}\ dx

    \int \sqrt{tan x}\ dx

    I only had questions and answers, and always ended up with a slightly different looking (but equivalent) answer to those supplied (because of using a different method)
