A = K1 O and B = K2 .
0 1 0 1O
L P L P
(a) Use A and B to show that matrix multiplication is not, in general, commutative. [2]
(b) Verify that A and B satisfy (AB) –1 = B–1A–1. [3]
2 In this question you must show detailed reasoning.
Find the acute angle between the vector 3i + 2j - k and the normal vector to the plane
2x + 3y + z = 6. [4]
