I am a physics student currently enrolled in an upper level
Electrodynamics course and, while playing around with Mathematica 3.0
for Students, I discovered that if I tell Mathematica to compute the
divergence of: unit vector(r) / r^2 it will return the value of
zero. However, I know that, at the very least in Electrodynamics, the
correct value should be: 4*Pi*(DiracDelta Function). Is it possible to
get Mathematica to output this value without explictly telling the
program that this is the value?
