I've learned from the TeXbook and from https://tex.stackexchange.com/a/128498/1340 that textmode fractions are often best written in slashed form. Looking at my manuscript I just ran into
$\frac{\partial t}{\partial x}$
, but partial derivatives in slashed form seem to be much less common (though I've indeed seen them sometimes, but others dislike them too, e.g., see comment How do I write the partial derivatives without partitioning?), especially when parentheses are needed.What's typographically appropriate there?
In fact, my actual code is
$\frac{\partial t}{\partial x, d_x}$
, because this isn't really calculus but some other notation (it's only inspired from partial derivatives) from a PhD thesis—which seems to never use slashed form. Still, if slashed form$(\partial t)/(\partial x, d_x)$
is appropriate I could use it.
EDIT: I know the , d_x
seems to make no sense—again, these are not actual partial derivatives. (I can link to the actual source but that's really off-topic).

form for partial derivatives either\frac
form or if inline use is more common switch to aD_{xyz}
style of notation.
