1. Mini-Quizzy on vectors:
I. Given A(5,2) and B(8,-1), find:
components

2. II. Given vectors u = (-3, 4) and v = (-7, -5), find:

3. III. Given vectors u = (5, 3) and v = (-7, 4):
a) Show the graphical representation of u + v, using the parallelogram rule.
b) | u + v |
Just to check:
(5, 3) + (-7, 4)
(-2, 7)
(5 + (-7) , )
(-2, 7)
b) | u + v |

4. WHAT IS THE DIFFERENCE?
I. Given A(5,2) and B(8,-1), find: VS
A(5,2) and B(8,-1) are endpoints of the one vector AB This is when you get the components by subtracting: the terminal minus the initial (B – A)
II. Given vectors u = (-3, 4) and v = (-7, -5), find: 5u + 6v
u = (-3, 4) and v = (-7, -5) are two separate and distinct vectors. Treat them as such. Do what is asked: multiply, add, subtract.
