Here's what I did. You will notice that the second derivative couldn't see the 'x', which had been replaced by psi. Yes, that is a “feature” of sympy, which assumes that all symbols that do not have an explicit dependence on the variable of differentiation are constants. Most of the time that works well. You can get around that by specifying that psi is a function of x. See the sympy documentation on functions. I have been fiddling with how to make it take more general derivatives, but need to figure out a definition of an infinitesimal that will function consistently within the sympy environment. I do like the equation annotation. (eq1), (eq2), (eq3), etc. Nice. Glad you like it. I sometimes collapse the code blocks. This then leaves you with the results of each step as might be provided in a traditional derivation. You can also pretty it up with comments in markdown cells between the each step.
