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

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!
