This is a u substitution too, right? Then you would do integration by parts, right?
For the second interval I got 1/2ln|u|. Is that correct?
there is no by parts here. regular substitution or a memorized formula will get you through
well, this level of algebraic manipulation doesn't slow me down really. at least not enough to warrant memorizing formulas that it is not the end of the world if i don't memorize themActually, this helps when you're giving a test at the college, isn't?
