True or False: u v = for any two vectors u and v in n b. True or False: u2+ v2= u + v2for any two vectors u and v in n c. True or False:

a. True or False: u − v = for any two vectors u and v in ℜn

b. True or False: u2+ v2= u + v2for any two vectors u and v in ℜn

c. True or False: u + v2+ u − v2= 2 u2+ 2 v2for any two vectors u and v in ℜn
