A silly question
no, we say "the partial of f with respect to x"
are you looking for a short phrase? for instance, for $\displaystyle \frac {dy}{dx}$ virtually no one says "the derivative of y with respect to x" most people just say "dy dx." is it something like this you are looking for?
Hello,
have a look here: Partial derivative - Wikipedia, the free encyclopedia
By the way: Your signature should be printed like this:
Hi,
I'm going to try:
$\displaystyle
\mathfrak{Diophantine~ equation@:~ A ~child ~can~ under]and, ~only ~a ~ma]er~ can ~solve.}
$
Obviously no . So sorry!
You have to use a typographically correct font with 2 different characters of "s" depending where it is placed in the word. Additionally you have to use ligatures between "s" and "t", double "l" (that's a lower case of a capital L), "f" and "t" and in German there are a few characteristical combinations of letters: "sch" or "ch" or "ck"...etc.
In the font I use (it is obviously not the font $\displaystyle \mathfrak{Fraktura}$ of the MHF) you find those exceptional characters at places of brackets or the @-sign.
