Question One (a) In a two-dimensional cartesian coordinate system, a is the position vector from the origin to the point (1,0), b is the position vector with length 2 at angle 60 (counterclockwise) to the positive x-axis. Describe the vector b a. (b) The figure below shows the triangle OAB 0 7 B The point M is the midpoint of OA and point N is the midpoint of OB. Let OM = a, and ON = b. By finding simplified expressions for MN and AB, in terms a and b. Show that MN is parallel to AB, and half its length. NELSON K.
