The following sequence of commands in the notebook... x = var('x') n = var('n') assume(n>0) integrate(x^n, x)
...results in "n+1" if I don't have the "Typeset" box checked, and if I do have it checked, I sometimes get "\newcommand{\Bold}[1]{\mathbf{#1}}n + 1" and I sometimes get "n + 1", neatly typeset. If I do something like "integrate(sin(n*x), x, 0, pi)", I get "nn" in either case (although with typesetting, the n's are typeset). In a terminal, everything works fine. This is with version 4.1 on Ubuntu. What on earth is happening here? (I am teaching some basic Fourier series stuff this semester, so I *need* to be able to integrate stuff with sin(n*x) and cos(n*x) in the notebook, so I can publish the worksheets for students!)
