# Vectors: Cross Products and Orthogonality

1. Find the cross product a X b and verify that it is orthogonal to both a and b.

2. a = < 5,1,4 >, b = <-1,0,2>

3. a = 2i + j - k, b = j + 2k

4. Find |u X v| and determine whether u X v is directed into the page or out of the page. (Please view the attachment to view the diagram pertaining to this question)
