The video tutorial explains how to find the component form of a vector given its initial and terminal points. It demonstrates sketching the vector on a coordinate plane and calculating its X and Y components. The tutorial then covers determining a unit vector in the same direction by calculating the vector's magnitude and performing scalar multiplication. Finally, it presents the results graphically, showing the original vector and the unit vector.

What are the initial and terminal points of vector v?

• (4, -2) and (1, 3)

• (1, 3) and (4, -2)

• (0, 0) and (1, 3)

• (4, -2) and (0, 0)
