Find the unit vector with the same direction as another vector given

The video tutorial explains how to find a unit vector by first calculating the magnitude of a given vector in component form. It demonstrates the process of deriving the unit vector by dividing each component by the magnitude, and discusses the concept of scalar multiplication. The tutorial also emphasizes the importance of rationalizing denominators in the final answer.

Explain how the scalar is used in relation to the vector in the text.
