Question

If v initial is (-3,7) and terminal is (2,4), find the unit vector of v in the most simplified form.

Answer 1

Answer:

$(\frac{5}{\sqrt{34}} ,\frac{-3}{\sqrt{34}} )$

Step-by-step explanation:

The vector v:

(2,4)-(-3,7)

=(5,-3)

norm:

||(5,-3)||=$(5^2+3^2)^{ 1/2}=\sqrt{34}$

unit vector:

$(\frac{5}{\sqrt{34}} ,\frac{-3}{\sqrt{34}} )$
