Was something like that generally what you had in mind?

I've begun adding other examples for the API of `eombase`. One addition is the ability to pass in coordinates and speeds together or a single states iterable giving the user...

I have started a documentation page where I have placed all three examples. I am currently changing them from their code form to documentation format and have then I will...

Your plot trajectories comment has been addressed along with the other items we've discussed thus far.

I have put my notes that I have regarding equations of motion "forms" that I have found so far on my [website](http://jbm950.github.io/notes/dynamics/dynamics_main.html). Most sources that I have found are only...

I have written the rest of the public attributes and methods into the example. If there are any I missed or didn't think of let me know. I'm going to...

@angadhn or @moorepants could someone do a review of the .rst file? Also I think the check failed because of a change to numpy.

``` python >>> symsystem2 = system.SymbolicSystem(states, comb_implicit_rhs, ... mass_matrix=comb_implicit_mat, ... alg_con=alg_con_full, ... coord_idxs=(0, 1)) >>> symsystem3 = system.SymbolicSystem(states, dyn_implicit_rhs, ... mass_matrix=dyn_implicit_mat, ... coordinate_derivatives=kin_explicit_rhs, ... alg_con=alg_con, coord_idxs=(0, 1), ... speed_idxs=(2, 3))...

Was looked at and discussed in [PR #11117](https://github.com/sympy/sympy/pull/11117) in the sympy repository
