Finding the component form and magnitude of a vector

The video tutorial explains how to graph a vector and identify its initial and terminal points, P and Q. It then demonstrates how to calculate the component form of the vector using the coordinates of these points. The tutorial further explains how to determine the magnitude of the vector by applying the distance formula. The process involves squaring the differences of the coordinates, summing them, and taking the square root to find the magnitude.
