 Orthogonality (mathematics)

In mathematics, orthogonality is a concept that describes a relationship between vectors in a vector space. Two vectors are said to be orthogonal if their dot product is zero. This concept can be extended to various contexts in mathematics, particularly in linear algebra and functional analysis. Here are some key points regarding orthogonality: 1. **Geometric Interpretation**: In a geometric sense, orthogonal vectors are at right angles (90 degrees) to each other.
