TheTwothetwo [Collect summaries of section 10.4] Paradox I asked you to think about for today: Let u be a vector such that |u|=1. Choose a vector v such that |v| = 3 and u v = 5. Now we have |u–v| 2 = (u–v) (u–v) = u u – 2(u v) + v v = 1 – 2(5...
Looks at the misconception that the cross product of two vectors is simply another vector. Inadequacies created by such a misconception; Easy explaination of the cross product of two vectors; Concept of multiplication of two vectors; Defining the familiar multiplications involving two vectors; Problems...

1. When you complete a cross product between two vectors, what is the nature of the result you get? The result is a vector. The result is a scalar. The result can either be a vector or a scalar. The result is both a vector and a scalar. ...
cross′ prod`uct n. a vector perpendicular to two given vectors and having magnitude equal to the product of the magnitudes of the two vectors multiplied by the sine of the angle between them. Also calledvector product. [1925–30]
The cross product of the vectors = a_1,a_2,a_3 and = b_1,b_2,b_3 is the vector* =(vma
We know that the magnitude of the cross product of two vectors is the product of their magnitudes and the sign of the angle between the two vectors, which completes our proof. ◻ Preliminary definitions Definition 1 A regular curve is a connected subset γ of R3 homeomorphic to some G ...

Definition 4.1: Vector Product The vector product of two vectors, u and v, in three dimensions is defined as a new vector denoted by u×v, which has the following properties: (1) u×v is orthogonal to both u and v. (2) ‖u×v‖=‖u‖‖v‖sin[u,v]. (3) The vector...
