The most common definition is
\define\dif{\mathop{}\!\mfunction{d}}
(I don't know enough of ConTeXt, so may be {\tf d} is better than
\mfunction{d}).
The important part is \mathop{}\! which will add the space on the left
automatically when it's needed (for instance in \frac{\dif x}{\dif y}
no space is added).

Hello,
how to typeset differential in math correctly?
Here are my attempts:
---- \definemathcommand[dif][nolop]{\mfunction{d}} % Based on http://wiki.contextgarden.net/Math/functions
\starttext \startformula \sin x {\tf d} x \stopformula
\startformula \sin x \dif x \stopformula \stoptext ----
But:
- case 1: there is no space between "d" and "x" (should be similar to that between "sin" and "x")
- case 2: "d" in the formula is shifted down (?!) somehow.
So - ?
Other questions:
I need to typeset some math text.
- Variables should be typeset slanted, which is OK (see "x" in the example).
- Functions (sin, log... "d" in df/dx) should be typeset non-slanted - I guess \definemathcommand is supposed for this (or is there a better way?).
- Vector variables should be typeset bold slanted - is there a special command for this? (\vec adds arrow above the expression, so it is not supposed for this).
Thank you in advance.
Best regards,
Lukas
