    Finding a Unit Vector

    Hello.

    I have to find a unit vector in a direction of a given vector, which is listed below:

    w = i - 2j

    What I did was i plugged in < 1, 0> for i and < 0, 1> for j. I got

    < 1, -2 >

    but I'm not sure how to proceed.

    Any help will be appreciated.

    Step 1. Find the length of the given vector.
    Step 2. Multiply the vector by in inverse of its length.

    \frac{w}{{\left\| w \right\|}}
