Period____
Find the direction angle for each vector.

1) 18i - 24j 2) 5i - 12j

3) 10i - 27j 4) CD where C = (7, 9) D = (3, -9)

5) -42i + 29j 6) b = 2, -2

7) CD where C = (6, -5) D = (-3, -4) 8) CD where C = (6, 0) D = (-2, 7)

Find the component form of the resultant vector.

9) f = -1, -1 10) f = 3, -7
v = -8, -1 v = -10, 8
Find: -f - v Find: f - v

11) u -5, 1 12) f = 5, -9

v = -9, -5 b = -2, -11
Find: -u + v Find: -f + b

13) f = -6, 0 14) u = 11, 1
v = 0, -10 g = 4, 6
Find: f - v Find: u + g

15) f = -5, 3 16) Given: A = (5, 2) B = (8, 3)
b = 3, 9 Unit vector in the direction of AB
Find: f + b
