Woeginger, Gerhard J. When Cauchy and Hölder met Minkowski: a tour through well-known inequalities. (English) Zbl 1227.97035 Math. Mag. 82, No. 3, 202-207 (2009). Summary: The article presents concise and simple proofs for several classical inequalities, like the Cauchy inequality and the Minkowski inequality. All proofs proceed in exactly the same way, and they all exploit the concavity of an underlying function in exactly the same way.
