Vector Addition and Methods

The video tutorial covers operations with vectors, including addition, subtraction, and scalar multiplication. It explains how to add and subtract vectors using component form and demonstrates scalar multiplication by a constant. The tutorial also explores graphical methods for vector addition, such as the head-to-tail and parallelogram methods, to find the resultant vector.
