Interesting Facts About Dot Product

• Dot product represents projection of one vector onto another.
• It is commutative: A · B = B · A.
• Zero dot product indicates orthogonal vectors.
• Widely used in physics, computer graphics, and engineering.
• Helps in calculating angles between vectors using cos θ = (A · B) / (|A||B|).
