is that what you mean?

3. You say "partial derivative of .... to respect to ... "

Note: I am not really sure from where this symbol is taken from. It is not Greek, I can say that.

Thanks, but how do you pronounce the letter $\partial$?

"partial"

Can we say partial f over partial x for the notation?

no, we say "the partial of f with respect to x"

are you looking for a short phrase? for instance, for $\frac {dy}{dx}$ 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?

Thank you so much.

Another way of reading this is:

"partial of x over partial of y" or "partial d of x over partial d of y"

Hello,

have a look here: Partial derivative - Wikipedia, the free encyclopedia

By the way: Your signature should be printed like this:

It is from the Cyrillic alphabet.

Hi,

I'm going to try:

$
\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 $\mathfrak{Fraktura}$ of the MHF) you find those exceptional characters at places of brackets or the @-sign.
