Question

find the direction of w, given w=5i-3j

Answer 1

How shall we report it? Maybe an angle from the positive x-axis?

Answer 2

im not quite sure what that means, or how to go about it

Answer 3

What if it were a point on a cartesian coordinate system. Which way do you have to look to find (5,-3) when you are standing at the Origin?

Answer 4

to the left in quadrant II

Answer 5

?? No, it's in Quadrant IV.

Answer 6

OHH right right my bad wow

Answer 7

Perhaps the question is asking for the unit vector

Answer 8

Maybe: Or \(\theta\) in the 4th Quadrant, given \(tan(\theta) = -3/5\)

Answer 9

what if it is for vectors, because thats what this chapter is all about

Answer 10

Well, how are you reporting vectors? You get only Magnitude and Direction. What are the units for "Direction"?

Answer 11

It's probably the unit vector. You can way w is a vector of length |w| in the w/|w| direction

Answer 12

As good a choice as any.
