Latex typesetting of sub expressions also seem to be broken. This is probably caused by pynac not passing on the printing context when it calls the print function on the subexpression, though I haven't looked at any code yet.

Here is an example:

sage: var('kappa')
sage: x = sqrt(kappa)
sage: latex(x)
sage: F = exp(x)
sage: F
sage: latex(F)

Burcin: It seems the problem of sub-expression not getting typeset properly is specific to exp function. I could get it working by adding the _latex_composition method to class Function_exp (sage.functions.log) as

    def _latex_composition(self, x):
        from sage.misc.latex import latex
        return "e^{%s}"%(latex(x))

Note: My sage copy has patch #5711 applied on it.

  • Description modified (diff)
  • Summary changed from typesetting symbolic integrals broken to typesetting exp sometimes broken

This was about typesetting integrals, but since a description of exp not typesetting properly was added to this and #5711 is now largely about the typesetting of integrals etc., it seemed wise to change the description and summary. The commentary above seems pretty useful!
