Problem :
What is (1, 4, - 3) + 2(0, 1, 5)?
(1, 6, 7)
Problem :
If a creature was initially sitting at the point (3,4) in the plane, and
then moved to the point (-2,5), what is the vector which describes the
creature's displacement?
If
v is the displacement vector for the creature, we have that
(3, 4) + v = (- 2, 5). Solving for
v yields
v = (- 5, 1).
Problem :
Express the vector (2, 2, 5) in terms of unit vectors.
(2, 2, 5) = 2i +2j +5k.
