The video tutorial explains how to find the dot product of two vectors, U and W, and determine the angle between them. It begins with an introduction to the vectors and the task, followed by a detailed explanation of the dot product and its calculation. The tutorial then demonstrates how to calculate the dot product and discusses the angle between vectors using the cosine formula. It also covers how to calculate the magnitude of vectors. The video concludes by explaining orthogonality and the concept of perpendicular vectors.
