What is the meaning of ∇ F?

Definition. The gradient of the function f(x,y) = −(cos²x + cos²y)² depicted as a projected vector field on the bottom plane. The gradient (or gradient vector field) of a scalar function f(x₁, x₂, x₃, …, x_n) is denoted ∇f or ∇→f where ∇ (nabla) denotes the vector differential operator, del.

What is the inverted delta function?

An inverted delta would be the gradient operator. It is usually written out as 'grad' when you don't have math typesetting available. It is a vector operator, with each element of the vector being the partial derivative, or slope, of the function being operated upon in one of three directions in space.

The nabla is a triangular symbol resembling an inverted Greek delta: or ∇. The name comes, by reason of the symbol's shape, from the Hellenistic Greek word νάβλα for a Phoenician harp, and was suggested by the encyclopedist William Robertson Smith in an 1870 letter to Peter Guthrie Tait. ∇

What is the upside down delta symbol in calculus?

The upside down delta symbol (∇) is often used in mathematics and science to represent the gradient of a scalar field or a vector field.

What is an example of an inverted delta?

The Sacramento-San Joaquin Delta has this classic, triangular shape but with a major caveat — it's inverted. That is, instead of the delta splitting into numerous channels in a downstream direction, it is characterized by numerous channels coming together in a downstream direction.
