The video tutorial covers three methods to write vectors: component form, linear combination, and using magnitude and angle. It explains the component form with initial and terminal points, the linear combination using unit vectors I and J, and the magnitude-angle form using cosine and sine functions. The tutorial also includes a practical example of calculating a vector's components using magnitude and angle, emphasizing the importance of simplifying answers and rounding appropriately.
