WebAnswer (1 of 6): Technically not. A dot product is a bilinear/sesquilinear operator that takes two vectors in a finite dimensional vector space. Differential operators lie in a different space than the functions they act on. Often we write an operator operating on some object the same way we do... WebThe outer product between two vectors, U, and V, gives us a matrix. Every matrix acts as a transformation on vectors. That is, given a vector, W, their outer product transforms W into another vector. Now, this might be obvious to you, but what obviously isn’t so obvious is what it transforms it into. Specifically,

WebThey have different formulas: The divergence formula is ∇⋅v (where v is any vector). The directional derivative is a different thing. For directional derivative problems, you want to find the derivative of a function F(x,y) in the direction of a vector u at a particular point (x,y). It can be any number of dimensions but I'm keeping it x,y for simplicity.

As a result the dot product of the vectors would be zero. The term orthogonal includes the definition of normal/perpendicular vectors, but it also includes the case of the zero vector. A zero vector is orthogonal to all vectors including itself. 1 comment

http://www.ees.nmt.edu/outside/courses/GEOP523/Docs/index-notation.pdf In linear algebra, the outer product of two coordinate vectors is a matrix. If the two vectors have dimensions n and m, then their outer product is an n × m matrix. More generally, given two tensors (multidimensional arrays of numbers), their outer product is a tensor. The outer product of tensors is also referred to as their tensor product, and can be used to define the tensor algebra. The outer product contrasts with:
