The video tutorial explains how to find the component form and magnitude of a vector. It begins with an introduction to the problem, followed by a graphical representation of the vector using initial and terminal points. The tutorial then details the steps to calculate the component form by subtracting the coordinates of the initial point from the terminal point. Finally, it demonstrates how to calculate the magnitude of the vector using the Pythagorean theorem, resulting in a magnitude of 15. The tutorial concludes with a summary of the findings.
