Hi all, Does anyone know how to use cylindrical polars with SymPy's vector module?
I just saw this SO question here: https://stackoverflow.com/questions/68767945/how-do-i-work-with-vectors-in-cylindrical-and-spherical-systems-with-sympy We can define a coordinate system like this: In [25]: from sympy.vector import CoordSys3D ...: ...: N = CoordSys3D('N', transformation='cylindrical') In [26]: N.base_scalars() Out[26]: (r_N, theta_N, z_N) In [27]: N.base_vectors() Out[27]: (i_N, j_N, k_N) Although the scalars are r, theta and z the unit vectors are i, j and k. How would I get vectors like e_r and e_theta to work with those? Oscar -- You received this message because you are subscribed to the Google Groups "sympy" group.
