High Quality Content by WIKIPEDIA articles! In vector calculus, del is a vector differential operator, usually represented by the nabla symbol. When applied to a function defined on a one-dimensional domain, it denotes its standard derivative as defined in calculus. When applied to a field (a function defined on a multi-dimensional domain), del may denote the gradient (slope) of a scalar field, the divergence of a vector field, or the curl (rotational) of a vector field, depending on the way it is applied. Strictly speaking, del is not a specific operator, but rather a convenient mathematical notation for those three operators, that makes many equations easier to write and remember. The del symbol can be interpreted as a vector of...
