How to find a unit vector with the same direction as 8i - j + 4k?

Allison Hurst

In the identical direction. keep the components' sign configuration (+ - +) constant.
For any vector u, the unit vetor in the direction of u is $\frac{1}{|u|}u$, where $|u|=\sqrt{}$(sum of the squares of the magnitudes of the components of u).
Here. it is $\frac{1}{9}\left(8i-j+4k\right)$
