This problem, however, seems to be a more general case. We can thus apply the Pythagorean theorem to. The Cauchy—Schwarz inequality allows one to extend the notion of “angle between two vectors” to any intetrales inner-product space by defining: The Cauchy—Schwarz inequality can be proved using only ideas from elementary algebra in this case.
Another generalization is a refinement obtained by interpolating between both sides the Cauchy-Schwarz inequality:. Views Read Edit View history. The Mathematical Association of America.

I like a lot the second one! Theorem Kadison—Schwarz inequality,   named after Richard Kadison: From Wikipedia, the free encyclopedia. Use the Cauchy-Schwarz inequality. In this language, the Cauchy—Schwarz inequality becomes .

A Modern Introduction to Its Foundations. Petersbourg7 1: Email Required, but never shown. The triangle inequality for the standard norm is often shown as a consequence of the Cauchy—Schwarz inequality, as follows: Riesz extension Riesz representation Open mapping Parseval’s identity Schauder fixed-point.
We prove the inequality.
Equivalently, by taking the square root of both sides, and referring to the norms of the vectors, the inequality is written as  . I know two beautiful direct proofs of this fact.
