How to find the direction of a vector as a linear combination

The video tutorial explains how to represent vectors as AI plus BJ and find the directional angle using the tangent function. It demonstrates calculating Theta by taking the inverse tangent of a ratio, resulting in a 45-degree angle in the first quadrant. The tutorial concludes with a confirmation of the angle's correctness.
