Question

Evaluate the expression:

v ⋅ w

Given the vectors:

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

Okay this is the last one I promise!

Answer 1

the dot product of two vectors is the sum of the corresponding products of the components

Answer 2

can you explain a little more please(:

Answer 3

say\[p=\langle p_1,p_2,p_3\rangle\]\[q=\langle q_1,q_2,q_3\rangle\]

\[p\cdot q=p_1 q_1+p_2 q_2+p_3 q_3\]

Answer 4

so do I do that for r and v....

Answer 5

no, v and w
