i need some math help
 

im trying to integrate

S re^(r/2) dr

so i go

[u=r dv=e^(r/2)dr]
[du=dr v=e^(r/2) ]

S re^(r/2) dr = re^(r/2) - S e^(r/2)dr
S re^(r/2) dr = re^(r/2) - e^(r/2)

however the answer i should get is

2(r-2)e^(r/2)

i dont get it

bump for me

lol, i think you might be looking for help in the wrong place...

Seven, I'm pretty sure the answer is seven.

is that your final answer?

I would like to call Squishipimp .....

i got sick of this shit and smoked some pot for the first time in a year or so.. damn this feels good :)

what are you going to call him?

Your task is http://www.sosmath.com/tables/integr...7/integ27.html under 2.

Other then that, your error is dv=e^(r/2)dr => v=e^(r/2) :error :error :error

what was that equation?
its really hard... uh..

i never go on math classes...

hmm, i forgot already calculus! ^_^\/

Look for the ^

It's all in the ^

I got a headache looking at that.

I am choosing "call to a friend".

Yup...

LOL, god I hated math and now I remember why.

bump for suckass math ;)
