Re: Partial Derivatives

Hi;

∂ is called "del" or "dee" or "curly dee"

I did not know that, I just called them partial y, partial x etc.

All the examples check out, nice page!

Re: Partial Derivatives

Thanks everyone!

I have also heard "day", so they say "day-f day-x" but that doesn't seem common.
