Notations of Gradient 

In vector calculus, the grad symbol is the vector calculus gradient operator. It is used to represent the grad function, which takes one argument which should be a scalar-valued function and returns a vector of functions.

Description of this symbol

• Grad in OpenMath and in MathML
• Grad also is described in MathWord and in Wikipedia

Observations of Gradient

German

We find in the example on the right that the german book Rechenmethoden der Physik represents the gradient in page 206
and it is called 'Gradient' in German context.
