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
