7.2 Vector Properties (#theoreticaltools) Determine whether the following statements are true or false. If true, provide a brief justification. If false, give a counterexample. (a) u v=vu for vectors u, in R³ (b) ||cu|cu|| for constant c in R and u in R³ = (c) u (vw) = uv-u w for vectors u,, w in R³ .
