Write a vector in component form and find the magnitude

The video tutorial explains how to determine the magnitude of a vector given as a directed line segment. It covers two methods: converting to component form or using the given format directly. The process involves labeling points, calculating differences, and simplifying the result to find the magnitude. The final answer is presented as 2 sqrt 41.
