The gradian is not part of the International System of Units (SI). The EU directive on the units of measurement [20]: 9–10 notes that the gradian "does not appear in the lists drawn up by the CGPM, CIPM or BIPM." The most recent, 9th edition of the SI Brochure does not mention the gradian at all. [22]
The nabla symbol, written as an upside-down triangle and pronounced "del", denotes the vector differential operator. When a coordinate system is used in which the basis vectors are not functions of position, the gradient is given by the vector [ a ] whose components are the partial derivatives of f {\displaystyle f} at p {\displaystyle p} .

Gardiner's sign list is a list of common Egyptian hieroglyphs compiled by Sir Alan Gardiner. It is considered a standard reference in the study of ancient Egyptian hieroglyphs. Gardiner lists only the common forms of Egyptian hieroglyphs, but he includes extensive subcategories, and also both vertical and horizontal forms for many hieroglyphs.
the nabla symbol Del , or nabla , is an operator used in mathematics (particularly in vector calculus ) as a vector differential operator , usually represented by the nabla symbol ∇ . When applied to a function defined on a one-dimensional domain, it denotes the standard derivative of the function as defined in calculus .
Typographical symbols and punctuation marks are marks and symbols used in typography with a variety of purposes such as to help with legibility and accessibility, or to identify special cases. This list gives those most commonly encountered with Latin script. For a far more comprehensive list of symbols and signs, see List of Unicode characters.

In Cartesian coordinates, the divergence of a continuously differentiable vector field = + + is the scalar-valued function: = = (, , ) (, , ) = + +.. As the name implies, the divergence is a (local) measure of the degree to which vectors in the field diverge.
