Im going to take a functional approach to inequality proofs: Rather than discuss inequalities from
axiomatic basics, I want to show you the heuristics involved in proving inequalities.
Here are a couple of basic rules which Ill
Diagonalization of a 2 2 real symmetric matrix
Consider the most general real symmetric 2 2 matrix
where a, b and c are arbitrary real numbers. In these notes, we will compute the
eigenvalues and eigenvectors of A, an
