The dot product A·B = |A||B|cos(θ) produces a scalar measuring how much two vectors point in the same direction. A·B=0 means they are perpendicular. Fundamental in physics, machine learning, and computer graphics.

Fun Fact

The dot product is the foundation of cosine similarity — used by search engines and recommendation systems to compare documents represented as vectors.
