I agree that the demo site is looking great. Although, I think that sharing
a theme with other projects might be something desirable.

I have the following ODE
z'' = 1 - z²
That has as solutions z=tanh(C + t) and z=coth(C + t), depending on the
initial condition being greater or less than 1. When I use dsolve I get the
latter
from sympy import *
init_session()
ode = Eq(f(t).diff(t), 1 - f(t)**2)
sol = dsolve(ode, f(t))
Do you have a Minimal Working Example (MWE)?

I can confirm a bug here.
When I run
theta = symbols("theta")
integrate(cos(3*theta)/(5 - 4*cos(theta)), (theta,0,2*pi))
it returns
67*pi/24
instead of pi/12. It does work for me, though.

This is great and the quality of the 3D plots is incredible.
Regarding the backends, did you try PyVista? That one is also based on VTK
and it works nicely in MyBinder.

I agree that this would be good for the project but maybe it would be a
good idea to polish the documentation a bit. Some of the pages in the wiki
are somewhat outdated and they are on the first results in a web search.

Hi Aaron,
I think that we could ask in Twitter, maybe somebody know some application.
Looking in the papers that we have collected I found the following:

You could also use a package that I wrote for that purpose
https://continuum-mechanics.readthedocs.io/en/latest/
If you are interested in Cartesian coordinates only you could just do the
following
u = Matrix([x, 2*y*z, 3*x*y])
J = u.jacobian([x, y, z])
H = Array([J[:, k].jacobian([x, y, z])
I should have mentioned that the course where I use this tutorial is
Advanced Mathematics for Engineers. You mention two important points that
could be added if the tutorial is useful for the community.

I adapted Maxima's tutorial "Maxima in 10 minutes" to SymPy for one of my
courses. I would like to know if you consider useful to share it somewhere.
This is an nbviewer link:

I think that using a static generator would have advantages from the
translation point-of-view as well.

If you have a list of terms from similar projects, maybe we can crowdsource
the "glossary". If not, it can still be useful to have a document/site
where this terms can be added from some community members. Although, I
think that some kind of instructions are needed.

I just created a new issue (#19317) related to dsolve and Bessel equations.
The link is the following:
https://github.com/sympy/sympy/issues/19317
I didn't know if is customary to write in the mailing list about as well.
If that's not the case, please let me know.
Best,

You could check a module that I wrote in Continuum Mechanics
https://continuum-mechanics.readthedocs.io/en/latest/
It already has the gradient of a vector for orthogonal coordinates.

I have been working in a function that turn a higher-order system of ODEs into
a system of first order equations. So you think that it might help?
