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? Elvis Dieguez
