What is the direction of v   =   ( -3, 2, 4)T?

A good answer might be:

Calculate the unit vector:

  1. | v |2   =   9 + 4 + 16   =   29
  2. vu   =   v / 29

Right Angles

 

There is an interesting result when the directions of two vectors are 90o apart. For example, zero degrees and 90 degrees.


 

QUESTION 7:

What is the dot product of r   =   (6, 0)T with s   =   (0, 8)T?
