  • Ticket #28964 – Description

    initial v8  
     1This ticket fixes several problems related to the conversion of derivatives to and from sympy:
     2
     3- the derivative arguments were permuted when converting to sympy (comment:7)
     4- the conversion from Sage to sympy did not account for the case of variables with multiple occurences (comment:1)
     5- the first argument of the derivative was skipped when converting from sympy (comment:6)
     6- sympy returns arguments of type `sympy.core.containers.Tuple` which was not handled
     7- Sage's derivative does not accept tuples, so the arguments must be flattened
     8- sympy's derivative count is converted to rationals, so Sage's derivative must accept rational arguments
