Example: In mathematics, orthogonality is important for understanding the relationships between different vectors.

Definition: To make two or more things at right angles to each other or to make them independent from each other in a mathematical or geometric context.

Example: In linear algebra, we often orthogonalize a set of vectors to simplify calculations.
