I'm having problems with VectorAnalysis package.
Within the documentation center, the package loads and works fine.
But in a notebook, it seems to highlight Curl in red and neither Div
or Curl works properly.
Needs["VectorAnalysis`"]
{D[x^2 y, x] + D[ x z, y] + D[ x^2 y^3, z]}
Div[{x^2 y, x z, x^2 y^3}]
gives different answers.
{2 x y}
0
Curl[{x^2 y, x z, x^2 y^3}]
gives
{0,0,0}
I'm on windows vista home edition, 64 bit, Mathematica 8.0.
Does anyone else have this problem?
