CrossProduct

  

compute the cross product of Vectors and differential operators

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

CrossProduct(v1, v2)

v1 &x v2

Parameters

v1

-

Vector, Vector-valued procedure, or differential operator

v2

-

Vector, Vector-valued procedure, or differential operator

Description

• 

The CrossProduct(v1, v2) calling sequence computes the cross product (vector product) of v1 and v2, where v1 and v2 can be Vectors, vector fields, Student[VectorCalculus][Del], or Student[VectorCalculus][Nabla].

  

Note: You can enter vector fields as Vector-valued procedures or operators.

• 

The Student[VectorCalculus] package has an &x cross product operator that you can use in place of the CrossProduct command. For example, CrossProduct(v1, v2) is equivalent to v1 &x v2.

  

Also, Del &x F is equivalent to Curl(F).
