I wrote a bug report and fix in the source chat a couple of weeks ago. There was no response, so I guess I wrote in the wrong chat.
The calculus addon script has one glaring issue, and one small issue with an easy fix. The glaring issue is the inability to differentiate the constant zero function 0&p. that gives an error. The fix is here: https://github.com/jsoftware/math_calculus/pull/2 I think this should be fixed asap, as it also causes an error on double differentiation of a linear polynomial. 1 2&p. The other issue is differentiating a general f^g function, which currently gives an error, but is easily doable.
