You can see the changes I made after we merged your first example: https://github.com/pydy/pydy/commits/master

Hi Peter, made you could summarize the math here in this issue (as most won't have the book). Or maybe you can find a paper we can download that has...

I don't know how to tackle it. Maybe figure out who added them both as ask them about it.

So maybe the fix is "Documentation Style Guide" and "Docstring Style Guide" as the two names.

This seems to be happening on all of the Mathjax rendered equations.

Couple of updates on this: 1. Solving nonholonomic constraints for the dependent generalized speeds symbolically can result in expressions that are not numerically stable (potentially both causing divide-by-zero issues and...

> As the sequence of the entries in the speed_constraints list matters a lot, is it better to have the 'smaller' terms at the 'left' of the list ( small...
