Determine whether the following statement is true or false using a proof or counterexample. Assume that u, v, and w are nonzero vectors in ?3.u × (v - w) = (u × w) - (u × v)
What will be an ideal response?
(Answers may vary.) False. Let u = 
, v = 
, w = 
. Then u × (v - w) = 
, but
(u × w) - (u × v) = 
.
