whiteyellowjacket839Lv1in Algebra·5 May 2019 In proving the Pythagorean theorem in class, we saw that |u vector + v vector |^2 = ||u vector ||^2 + 2 u vector middot v vector + ||v vector ||^2. Moreover, from the "physics'" definition of the dot-product, i.e. u vector middot v vector = ||u vector || ||v vector || cos (theta) and the fact that cos (theta) lessthanorequalto 1, it is obvious that u vector middot v vector lessthanorequalto ||u vector|| ||v vector|| (called the Schwarz inequality). Use both of the above properties of dot-products and norms to prove the triangle inequality. All stops must follow loyally from one another, and must be justified.
