Example 7
Find the unit vector and direction cosines of the given vector. First find the length, then the unit vector, and then the direction cosines. (a) A = 2i + j
Unit vector = Direction cosines = (b) B = 5i  12j Unit vector = Direction cosines = (5/13, 12/13). (c) C = ¼j Unit vector = = j Direction cosines = (0, 1).
