GlyphIndexGradient label
Gradient of f: ∇f
This names the gradient of a scalar field f.
Nabla sign
Nabla ∇ appears in gradient, divergence, and curl notation. A dot or cross after it changes the operation being described.

3 code pointsMeaning and context
Nabla ∇ appears in gradient, divergence, and curl notation. A dot or cross after it changes the operation being described.
How to use it
Identify the scalar or vector field. Write ∇f for the gradient of f and ∇ · F for the divergence of F; the dot matters.
Examples
Divergence label
Divergence of F: ∇ · F
The dot distinguishes this operation from the gradient notation.
