Cross Product and Vector Normalization

This video tutorial explains how to find a unit vector that is orthogonal to two given vectors, U and V. The process involves computing the cross product of the vectors to find an orthogonal vector, verifying its orthogonality using the dot product, and then normalizing it to obtain a unit vector. The tutorial provides a step-by-step guide, including calculations and verification, to ensure the vector is orthogonal and normalized correctly.
