i know this is integration by parts so here is the problem I am currently confused on how the get an answer
r e^r/2 dr
I know I the formula is int udv= uv - int du v
what i am not getting is what to use for this one. I figured
e^r/2 = v and du = r
so u= r^2/2 and what will that make dv? i have always had trouble with this part.
so while i try another guys please help... make me not go insane...
