## delDel, also known as alted or nabla, is the vector
operator Δ, expressed in Cartesian
coordinates as
The product of Δ and a scalar S yields a vector field called grad S (the gradient of S):
The scalar product of Δ with a vector V is the divergence
of V (div); the vector product of Δ with V is the curl of V. ## Related categories• ALGEBRA• SYMBOLS AND NOTATION | |||||
