Orthogonality: Squaring Things Up
Lecture no. 19 from the course: Mastering Linear Algebra: An Introduction with Applications
Taught by Professor Francis Su | 32 min | Categories: Default Category
In mathematics, “orthogonal” means at right angles. Difficult operations become simpler when orthogonal vectors are involved. Learn how to determine if a matrix is orthogonal and survey the properties that result. Among these, an orthogonal transformation preserves dot products and also angles and lengths. Also, study the Gram–Schmidt process for producing orthogonal vectors.
