Question

Let u = <-4, 3>. Find the unit vector in the direction of u, and write your answer in component form.

Answer 1

unit vector u = vector u / magnitude u

vector u = (-4, -3)
magnitude u = 5

unit vector u = (-4,-3) / 5

unit vector u = 1/5(-4i -3j)

Answer 2

where i is your unit vector x component, and j is your unit vector y component

Answer 3

it's a scalar multiplied by a vector, which is the same as distributive property with normal numbers.

Answer 4

put it in component form, so it's similar to distributing normal numbers.

4( 7i -3j) - 3(-9i +5j)

Answer 5

55 -27:)
