Re: [sympy] new to sympy

If you have the git clone, just edit the code, and make sure to run the Python shell from within the git directory. If you do this, when you import sympy, it will import from the current directory. Another way is to always run ./bin/isympy, which will start an (I)Python shell and import everything

You might wish to be more general and implement vector analysis as a function of a metric tensor. See the following link - http://en.wikipedia.org/wiki/Curvilinear_coordinates#Vector_operations On 11/19/2014 10:34 PM, Lukas Zorich wrote: Thanks Jason! El miércoles, 19 de noviembre de 2014 1

Re: [sympy] New to sympy: Implement Spherical Coordinates in Vector module

Yes. It would be a good idea to restrict yourself to diagonal metric tensors (orthogonal coordinate system) then inverting the metric tensor is simple and the Jacobian matrix is also diagonal. If you have a metric tensor you would use the Christoffel symbols to calculate the derivatives of th

Re: [sympy] New to sympy: Implement Spherical Coordinates in Vector module

Note that a challenge with spherical coordinates is picking a convention (see https://en.wikipedia.org/wiki/Spherical_coordinate_system#Conventions). We either need to pick one and document it clearly, and always use it, or find a clean way to support multiple conventions. Aaron Meurer On Wed, No

Interesting function, can be really a useful workaround. Anyways, I think that the most polite way is to use assumptions, such as: >>> refine(sqrt(abs(sin(t)**2)), Q.positive(sin(t))) sin(t) Anyways, there's a bug while simplifying expressions made up of diffgeom's coord functions, example: In
