Sort of. In Russian, the cursive form of lower case Д is sometimes written as ∂, and sometimes as g. That's always been a little confusing to me. This wike article, http://en.wikipedia.org/wiki/Cyrillic_alphabet, has some good information.Mathitalian said:∂ is a letter of Cyrillic alphabet, right?

Anyway, I read:
[tex]\frac{\partial f}{\partial x}[/tex]
as "de" f over "de" x

Yeah, me, too. I always pronounce this as "partial of f with respect to x."discrete* said:To my knowledge, we say "partial". That's what I've always heard and was told a while ago.
Mark44 said:If you say "dee" f over "dee" x, someone listening would likely interpret this as the ordinary derivative instead of a partial derivative. There have been a number of times where I was helping someone with calculus over the phone. In such cases you have to be more clear than when you can see the work.
