dear all,
i was trying to do Integrate[ r^2 Exp[-a r^2], {r,0,Infty}] but MMA
couldn't simplify a term which clearly was zero.
next i tried integrating over {r,0,r} and then took the limit as r->Infty.
MMA had the same problem. i'm not interested in the answer since i
already know the answer. i'm interested in how to get the answer. i'm
sure it's obvious. can someone tell me?
peter
ps- i just bought the student's MMA 3.0 and MathTensor. i know that the
student version of mathtensor is not crippled----is the student version
of MMA crippled in any way?

You can sum some of the series some of the time,
But you can't sum all of the series all of the time.
