I'm trying to solve # 4 in the picture I've posted, and I've tried several methods but it keeps telling me my answers are wrong. I've gotten all the other problems in the assignment correct so I feel something in this problem must be tricky or different than simpler integration by parts problems?
Could somebody help me out or at least give me a start on what to do in this problem?
That's the thing though, I don't even know what to make u and dv in this problem because it seems like only one of the terms has a variable in it. I was using 3arctandt as u and 5t as dv but this already gives me problems, as I don't know what the derivative of dt would be, etc. That's why I said if someone could get me started at least I'd appreciate it...
