I think that you mean the partial derivative symbol.

I advise you to learn as much as you can about partial derivatives which are used with functions of several variables before you start dealing with the implicit functions. If you have any specific problems, write them below, because we do not know what bothers you.

No thanks. I don't have any exercise; can you give me an example exercise that combines the implicit function and derivative ("function"?!)...

I have a nice hard question. The question is to prove that the function

is impilicit function.
I have the solution too. But try to answer it.

I do not instantly know how to prove it and today I do not have enough time to find it out. Google is your friend. I am not a fan of proofs. I prefer physics

I would start by stating the definition of "implicit function".
