Are the vectors Orthogonal, Parallel or Neither

The video tutorial explains how to determine if vectors are orthogonal using the dot product. It covers the calculation of the dot product and its significance in identifying orthogonal vectors. The tutorial also demonstrates how to find the angle between vectors using the dot product and magnitude, emphasizing that orthogonal vectors have a 90-degree angle. The instructor further explains the use of cosine inverse to verify the angle and discusses the calculation of vector magnitudes.
