Curl of two vectors

Webthe cross product is a binary operation on two vectors in a three-dimensional Euclidean space that results in another vector which is perpendicular to the plane containing the two input vectors. Given that the definition is only defined in three ( or seven, one and zero) dimensions, how does one calculate the cross product of two 2d vectors? WebDec 27, 2016 · As we know cross product of any two vectors yields a vector perpendicular to plane containing both the vectors so is it same for the vector operator del crossed with a vector ∇ × F (curl of vector field F). if not why? ...
