The formula for the orthogonal projection

Let V be a subspace of Rn. To nd the matrix of the orthogonal projection onto V, the way we rst discussed, takes three steps: (1) Find a basis ~v 1, ~v 2, ..., ~v m for V. (2) Turn the basis ~v i into an orthonormal basis ~u i, using the Gram-Schmidt algorithm. (3) Your answer is P = P ~u i~uT i. Note that this is an n n matrix, we are ...

A QUICK PROOF OF THE CAUCHY-SCHWARTZ INEQUALITY

you know and love in R2, then the Cauchy-Schwartz inequality is a consequence of the law of cosines. Speci cally, uv = jujjvjcos , and cos 1. In case you are nervous about using geometric intuition in hundreds of dimensions, here is a direct proof. First, note that we have ww= w2 1 + w 2 2 + w 2 n 0 for any w.
