So I'm a bit stuck on this problem. As you can see from my work, I used some trig identities to manipulate tan(2x) to sin(2x)/cos(2x) in the numerator. I then rewrote sin(2x) as 2sin(x)cos(x), which I'm sure is necessary or not to solve the problem. I still have a 1/x when I separate the terms. I'm stuck at this step and I'm not quite sure where to go. Any suggestions? Thanks in advance.
