Tutorial Exercise
Use the vectors u =
(6, 6), v = (-5, 3), and w = (4, -6) to find the indicated quantity. State whether the
result is a vector or a scalar,
(u· 2v)w
Step 1
Recall a property of dot products which states the following.
c(u · v) = cu : v = u· cv
Using this property, rewrite (u · 2v).
(u· 2v) =
X (u v)
