1. For this question, we define the following vectors: u = (1,2), v = (?2, 3).

(a) Sketch following vectors on the same set of axes. Make sureto label your axes with a scale. i. 2u ii. ?v iii. u + 2v iv. Aunit vector which is parallel to v

(b) Let w be the vector satisfying u + v + w = 0 (0 is the zerovector). Draw a diagram showing the geometric relationship betweenthe three vectors u, v and w.

2. Let P 1 and P2 be planes with general equations P1 : ?2x + y? 4z = 2, P2 : x + 2y = 7.

(a) Let P3 be a plane which is orthogonal to both P1 and P2. Ifsuch a plane P3 exists, give a possible general equation for it.Otherwise, explain why it is not possible to find such a plane. (b)Let ` be a line which is orthogonal to both P1 and P2. If such aline ` exists, give a possible vector equation for it. Otherwise,explain why it is not possible to find such a line.
