What does a o with a line through it mean?

If you need more help can you give me the latex code for it and i can do a question with it contained thanks.

Hello,

? That's a greek letter, called "theta"

Or ? That's the empty set.

But since you put this in calculus, it's more likely the greek letter

Find a scalar function such that (x,y,z) such that F(x,y,z) = delta(upside down traingle) (x,y,z)

what do i have to do?

I have the equation F(x,y,z) by the way

The empty set makes no sense to me here. Are you sure it isn't find a scalar function such that ?

what does this mean?

Greek letter "phi"
Hadn't thought of this one
Here, it denotes a function/mapping.

is the gradient.
