  Harmonic, Geometric, Arithmetic, Heronian and Contraharmonic means have been
studied by many mathematicians. In 2003, H. Evens studied these means from
geometrical point of view and established some of the inequalities between them
in using a circle and its radius. In 1961, E. Beckenback and R. Bellman
introduced several inequalities corresponding to means. In this paper, we will
introduce the concept of mean functions and integral means and give bounds on
some of these mean functions and integral means.
