How to find the magnitude and unit vector from a given vector

The video tutorial explains how to find a unit vector in a given direction. It begins by discussing the properties of unit vectors, including their magnitude of one. The tutorial then covers how to express vectors in component form and how to draw them. The process of calculating a unit vector is detailed, including the formula V over the magnitude of V. The video also demonstrates simplifying square roots during calculations and concludes with the final steps to obtain the unit vector.
