## Homework Statement

Find a unit vector in the direction of the given vector w=-i-2j

## Homework Equations

## The Attempt at a Solution

-i

_______

vertical -2j_________________

Could someone please show me how I would do it grafically and algebraically?

Do I just need to find the magnitude? Wouldn't any vector that has a negative x component and a negative y component work?

square root (-1)^2+(-2)^2=square root 5

Thank you very much
