4. Vector u is a scalar multiple of vector v. What can be concluded about: a. The dot product of these vectors. (Hint: there is a formula that connects the dot product of Cartesian vectors to the dot product of geometric vectors) b. The cross product of these vectors. (Hint: there is a formula that connects the cross product of Cartesian vectors to the dot product of geometric vectors) c. Provide an example for a. and for b. that illustrate your conclusions
