[color=#980000][b]Questions: [/b][/color][br][br][color=#000000]1) Is vector addition commutative? Explain why or why not. [br][br]2) Explain, in you own words, how to add any 2 vectors [i]geometrically[/i]. [br][br]3) Is it ever possible for the resultant (sum) of two vectors to be the zero vector? [br] If so, describe the relationship that must be true between these 2 vectors. [br][br]4) Can you devise a geometric method (like the one above) to [i]subtract[/i] 2 vectors? [br] If so, how would you do this? [/color]
