I was recently made aware that only variables should be in italics in
equations (see e.g. [1]
<http://tex.stackexchange.com/questions/33120/should-subscripts-in-math-mode-be-upright>,
[2]
<http://pleasemakeanote.blogspot.se/2010/07/italics-in-math-equations.html>,
[3] <http://physics.nist.gov/cuu/pdf/typefaces.pdf>).
I never really reflected over the distinction, but now it seems obvious.
Should we make LaTeX output of SymPy follow this?
e.g. change:
>>> x = sympy.Symbol('x')
>>> print(sympy.latex(sympy.Integral(x, x)))
\int x\, dx
to:
>>> x = sympy.Symbol('x')
>>> print(sympy.latex(sympy.Integral(x, x)))
\int x\, \mathrm{d}x
what do you think?
Best regards,
Björn
