Question

Find the components of the vector v with initial point P and terminal point Q. Find the unit vector u in the direction of v.

a. P: (1,1,0), Q: (6,2,0)
b. P: (1,1,1), Q: (2,2,0)

Answer 1

Answer:

Step-by-step explanation:

v=Q-P

v=(5,1,0)

u=v/(magnitude of v)=(5,1,0)/(\sqrt{5^2+1^2+0^2)

u=(5/5.09,1/5.09,0)

v=Q-P

v=(1,1,0)

u=v/(magnitude of v)=(1,1,0)/(\sqrt{1^2+1^2+0^2)

u=(1/$\sqrt{2}$,1/$\sqrt{2}$,0)
