I'm having trouble getting dsolve to work with a system of equations. If
possible I'd like to find a work around so I can continue the work I'm
doing...
I'm using IPython 3.4. Here's a simple test case:
from sympy import *
t,c,d=symbols(r't,c,d')
A,B=symbols(r'A,B',cls=Function)
Eq1=Eq(A(t).diff(t),B(t)-B(t).diff(t)+c)
Eq2=Eq(A(t),B(t).diff(t)+A(t).diff(t)+d)
Maybe just file an issue? dsolve for systems is a real mess, see e.g.,
https://github.com/sympy/sympy/pull/9235
I'm also not sure that form is supported. You could rework it by hand
isolate `A(t).diff(t)` and `B(t).diff(t)` as the two left-hand sides and
try again...
