This Demonstration draws the scalar multiple

c

of the vector

PQ

using the initial point

A

(so that the scaled vector is

AB

). You can view the horizontal and vertical components of the two vectors, as well as their magnitudes and direction (i.e., the angle they make with the positive

x

axis).
