Question

Let --->u =[2,-2,1] and --->v=[-3,5,-1]
(a) COMPUTE the distance between -->u and -->v .
(b) COMPUTE a unit vector in the direction of -->u

the arrows are over u and v.

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
