True/False: Determine whether each of the statements that follow is true or false. If a statement is true, explain why. If a statement is false, provide a counterexample.

(a) True or False: For any two vectors u and v in 3, u×v=v×u.

(b) True or False: If u and v are two vectors in 3, then u×v=u·v.

(c) True or False: If u×v=v×u, then u and v are parallel.

(d) True or False: If u, v, and w are vectors in R3, then (u × v) × w = u × (v × w).

(e) True or False: The triple scalar product can be used to find the volume of a parallelepiped.

(f) True or False: If u, v, and w are vectors in R3, then u · (v × w) = −v · (u × w).

(g) True or False: If u and v are nonparallel vectors in R3, then u · v u×v = cot θ, where θ is the angle between u and v.

(h) True or False: If u and v are unit vectors in R3, then u × v is also a unit vector.
