Find the Unit Vector U in the Same Direction as Vector W

The video tutorial explains how to find a unit vector from a given vector. It begins by introducing the concept of a unit vector and its formula, which involves dividing a vector by its magnitude. The instructor prefers to express vectors in component form for easier calculation. The magnitude is calculated using the Pythagorean theorem, and the unit vector is derived by dividing each component by the magnitude. The tutorial concludes with a demonstration of the final unit vector expression.
