WebThe Del operator#. The Del, or ‘Nabla’ operator - written as $\mathbf{\nabla}$ is commonly known as the vector differential operator. Depending on its usage in a mathematical expression, it may denote the gradient of a scalar field, the divergence of a vector field, or the curl of a vector field. WebWe have introduced a new property for a scalar valued function called the gradient. It can be found by taking the sum of all of the partial derivatives with respect to all of the variables (however many there may be). The …
