Hello all,
unfortunately I'm seeking help because I cant remember the name of a greek symbol from multivariable/vector calculus. $$\delta$$ i think this is the correct one. it looks like a d with the tail cut off, and is used for denoting a specific differentiation of a variable amongst multiple variables. thank you very much.

I think you want $$\partial$$

It's TeX code is \partial, and I've seen it called "curly-d" but I believe it is the italic lower-case "dey" from the Cyrillic alphabet.
