Then the symbol for the curl is del cross E.
-
So it'll be del W, del X, del W del X.
-
We don't have any integrals left as negative del squared Phi.
-
To compute the gradient, we use the del operator on the function.
-
The del operator can express the divergence of a vector field.

Etymology
Del in math is the short name for the small triangle symbol ∇ used in vector calculus to find how a field changes, like the gradient or divergence. A helpful way to remember it is to think of del as linked to derivative or 'difference', because it measures 'change' in space.
