Finding the angle of a vector as a linear combination

The video tutorial explains how to express vectors as components AI and BJ, and how to find the direction of an angle using the tangent function. It demonstrates calculating the inverse tangent with a calculator to find the angle in degrees. The tutorial emphasizes converting the angle to a positive value, especially when it lies in the fourth quadrant. The session concludes with a brief setup for future learning.
