t = tan(x/2) is almost magic for solving trig function integrals. It is sometimes considered almost cheating. Anyway, ...
Why not start with t = tan(x/2) and the other two pieces of information you have been given?
If you were me, you would probably want to start by checking the claims about dx and sin(x)! You'd find that they left out "dt" in the former. I never like to assume I've been told the truth ...View attachment 23360
I am really unsure of where and how to start. Any help is greatly appreciated!
You have not shared detailed work here. We cannot tell you 'what you are doing wrong" - unless you show us what you are doing!! Please post your detailed work.Thank you for your response! I did do that, but the answer is still not correct. What am I doing wrong?

As tkhunny mentioned, this is a substitution famous for its magical powers:Thank you so much everyone! I was doing it correctly, but I needed to switch the x to t and THEN substitute tan(x/2) for all the t's.
That was a weird one.
Appreciate the help!!
