What is the nabla used for?
Modern uses. The nabla is used in vector calculus as part of the names of three distinct differential operators: the gradient (∇), the divergence (∇⋅), and the curl (∇×). The last of these uses the cross product and thus makes sense only in three dimensions; the first two are fully general.
