Do you mean solve for
This is the wrong forum for this but my original problem is
So I used the integral identity
Then I rewrote the problem
So, if i could find a way to transform that secxtanx, then I would be home free...is that clear?
You do know that

which is what I come up with when I integrate this part
so I had the secxtanx left over and didnt know what to do with it
So what happened to the sec(x)tan(x)? shouldn't it be sec(x)?

there goes the light bulb! Thanks, I really appreciate it!
