If you have a negative definite matrix, then − M is positive definite, hence − u, v forms an inner product. By the Cauchy-Schwarz inequality, we get. − u, v 2 ≤ ( − u, u, ) ( − v, v ), which is equivalent to the inequality stated.

There are many different proofs of the Cauchy–Schwarz inequality other than those given below. When consulting other sources, there are often two sources of confusion. First, some authors define ⟨⋅,⋅⟩ to be linear in the second argument rather than the first. Second, some proofs are only valid when the field is and not This section gives proofs of the following theorem:
