Vector Operations and Components

The video tutorial explains the process of working with two-dimensional vectors U and W. It begins by defining the vectors with their X and Y components and graphing them. The tutorial then demonstrates how to scale vector U by 3 and vector W by 1/5, followed by plotting these scaled vectors. Finally, it shows how to add the scaled vectors to find the resultant vector, emphasizing the head-to-tail method for vector addition.
