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

Answer 1

Do you know how to find the magnitude of the vector?

Answer 2

kind of

Answer 3

Okay, you need to find the magnitude to get the answer, so can you find it or not?

Answer 4

Would I use \(\sf\sqrt{(v_1)^2+ (v_2)^2}\) ?

Answer 5

Yes

Answer 6

\(\sf\sqrt{4^2~+~3^2}\) \(\sf\sqrt{25}\) 5

Answer 7

That is right

Answer 8

That is the right magnitude, so now you just do scalar division
