The documentation on QRSolve states:

Changing this does indeed prevent some integrals from working, like
integrate(conjugate(x), x). We really need to separate the derivative used
by the heuristic Risch algo
Comment by brett_...@optusnet.com.au:
I have just started using sympy. I've been using it to equations of motion
using the Langrangian formulation, so I just need to state the KE and PE
formula and let sympy do the tedious and quite error-prone (when done by
