Question

Help--why would they give me r as a vector if its only asking for v ⋅ w ? (this is using dot products of vectors)

Evaluate the expression:

v ⋅ w

Given the vectors:

r = <8, 8, -6>; v = <3, -8, -3>; w = <-4, -2, -6>

Answer 1

Extra information to confuse you maybe :) ?

Answer 2

really?

Answer 3

Why would you need r if you are calculating v.w ? It's just extra information , maybe you need it for another problem.

Answer 4

agree with above. just calculate v dot w

Answer 5

okay. thank you:)
