In Exercises 15 and 16, mark each statement True or False. Justify each answer. Unless stated otherwise, B is a basis for a vector space V . 15. a. If x is in V and if B contains n vectors , then the B -coordinate vector of x is in ℝ n . b. If P B is the change-of-coordinates matrix, then [ x ] B = P B x , for x in V . c. The vector spaces p 3 and ℝ 3 are isomorphic.

15. a. If x is in V and if B contains nvectors, then the B-coordinate vector of x is in ℝn.
b. If PB is the change-of-coordinates matrix, then [x]B = PBx, for x in V.
c. The vector spaces p3 and ℝ3 are isomorphic.
Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
