Hi all,
I've been using Mathematica to check some of my calculations, and one of the
integrals,
4 Pi Integrate[r^2 Bra[r,t] Ket[r,t], {r, 0, Infinity},
Assumptions -> {Re[m^2*a/(m^2 + t^2*a^2*h^2)] > 0}]
// FullSimplify
yielded the result:
Out[176]=
2
3/2 m 3/2
a (-------------)
2 2 2 2
m + t a h
-----------------------
2
m a 3/2
(-------------)
2 2 2 2
m + t a h
which is 1. i'm more curious than anything else: how do i coax Mathematica to
reduce this seemingly simple expression?
why is Mathematica doing this?
thanks!
pete
