Sorry I had an error. ```python import sympy as sm import numpy as np import matplotlib.pyplot as plt from sympy.physics.mechanics import (dynamicsymbols, ReferenceFrame, Point, LinearPathway, CoulombKineticFriction, LinearSpring, KanesMethod, Particle) from...

I take that back. The sign is due to me making it negative. But the integration freezes otherwise.

Ok, that looks better! Why is there no difference in Coulomb and Coulomb + Viscous? Some integration routines fail on the force sign switch (or get bogged down). I guess...

Thanks for this contribution. I'm not sure I understand it fully. Is there a reason the integration must happen inside KanesMethod? From a quick look, it seems that the user...

We recently introduced the `Force()` object that is a named 2-tuple, with the idea that it we would migrate towards using that. If we support this 3-tuple, then we should...

The 3-tuple isn't consistent with the direction of the API. We've been working to move away from a simple tuple so that we can have more flexibility in defining forces....

As far as I remember, we do fall back to matplotlib latex rendering when used in jupyter and qtconsole. But maybe that has changed over the years.

We use IPython's `latex_to_png`: https://ipython.readthedocs.io/en/stable/api/generated/IPython.lib.latextools.html#IPython.lib.latextools.latex_to_png This defaults to matplotlib's renderer. If you adjust our printer settings you should be able to enable png printing for math. But I don't know...

If you are using the preview function, on quick glance it doesn't seem to connected up to matplotlib's renderer.

> would that be welcome? Yes, I think having preview be able to use the matplotlib latex backend would be helpful to many.
