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

The video tutorial explains how to find a unit vector by dividing a vector by its magnitude. It begins with an introduction to the concept of unit vectors and their formula. The instructor prefers writing vectors in component form to simplify the calculation of magnitude. The process involves squaring each component, summing them, and taking the square root, akin to the Pythagorean theorem. The tutorial concludes with the final calculation of the unit vector components and a brief recap.
