Vector ??⃑ is a scalar multiple of vector ?? . 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 conclusion
