In summary, the Cauchy Schwarz inequality is a fundamental inequality in mathematics that states the dot product of two vectors is less than or equal to the product of their magnitudes. It is used in various mathematical fields and has applications in real-world problems. There are multiple proofs for the inequality and several generalizations that apply to different mathematical objects.

Think of it as the dot product of two vectors. From that you can show that, although already obvious, [tex]\sin{(a+b)}\leq 1[/tex].
