Finding the angle between two vectors

The video tutorial explains how to find the angle between two vectors using the cosine formula. It begins by introducing the formula and then demonstrates the calculation of the dot product. The tutorial highlights that finding the magnitude is unnecessary when the dot product is zero, as the cosine of the angle will also be zero. It further explains how to use the cosine inverse to determine the angle, emphasizing the concept of orthogonal angles, which are perpendicular and measure 90 degrees.
