Find a unit vector that: A. Has the same direction as the vector u=(2,-7) B. Has the opposite direction as the vector u Solution Same Direction means any multiple of the numbers. Multiply both by 2 and we get (4, -14) Opposite Direction - Just change the signs (-2, 7).

1. Find a unit vector that:
A. Has the same direction as the vector u=(2,-7)
B. Has the opposite direction as the vector u
Solution
Same Direction means any multiple of the numbers.
Multiply both by 2 and we get (4, -14)
Opposite Direction - Just change the signs (-2, 7)
