Hi, Alan. > Here is galgebra/sympy code for vector derivatives in rectangular and > spherical coordinate with output annotated using latex -
I did have a look at the galgebra package, and I was able to define my scalar field and vectors and compute the gradient or directional derivative, just like with sympy.vector. Though it did require significantly more scaffolding that is likely to be opaque to my students. As I said, I’m just working through an intro multivariable calculus course with my kids, so I only need R3. What I didn’t find in galgebra was anything that addressed my core problem: idiomatically evaluating a scalar field at a point specified by a position vector from the origin. /rdj -- You received this message because you are subscribed to the Google Groups "sympy" group.
