TY - JOUR TI - New proofs of Fejer's and discrete Hermite-Hadamard inequalities with applications AB - New proofs of the classical Fejer inequality and discrete Hermite-Hadamard inequality (HH) are presented and several applications are given, including (HH)-type inequalities for the functions, whose derivatives have inflection points. Morever, some estimates from below and above for the first moments of functions $f:[a,b]rightarrow mathbb{R}$ about the midpoint $c=(a+b)/2$ are obtained and the reverse Hardy inequality for convex functions $f:(0,infty )rightarrow (0,infty )$ is established.
