Question

Evaluate the expression:

v ⋅ w

Given the vectors:

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

Answer 1

@amoodarya do you know how to approach this one?

Answer 2

This is a simple dot vector operation.
Just multiply the corresponding components of each vector, and find the sum.
\[v . w = v_{x}w_{x} + v_{y}w_{y} + v_{z}w_{z}\]

Answer 3

if that's all that I have to do why do they give me R? @iPwnBunnies

Answer 4

Just to throw you off. xD

Answer 5

Extraneous information.

Answer 6
