Question

Evaluate the expression:

v ⋅ w

Given the vectors:

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

Answer 1

Am I on the right track here? :
The equation to be setup is (3)(-4)+ (-8)(-2)+ (-3)(-6)

Which equals (-12)+ (16)+ (9)

Which equals 22.

Answer 2

if that is v dot w, then yes that's correct

Answer 3

how can 4 + 9 = 22 ? :) you miss timing the third number there :)

Answer 4

oh didn't see the (9), that should be a (18)

Answer 5

Wow. That's the part I mess up. /idiot. Sorry about that. So is that literally all there is to this problem?

Answer 6

its fine, happens to all of us and yes that's all there is to it
