A Trigonometric Proof of Oppenheim’s and Pedoe Inequality

Authors: Israel Meireles Chrisostomo
Comments: 7 Pages.

This problem first appeared in the American Mathematical Monthly in 1965, proposed by Sir Alexander Oppenheim. As a matter of curiosity, the American Mathematical Monthly is the most widely read mathematics journal in the world. On the other hand, Oppenheim was a brilliant mathematician, and for the excellence of his work in mathematics, obtained the title of “ Sir ”, given by the English to English citizens who stand out in the national and international scenario.Oppenheim is better known in the academic world for his contribution to the field of Number Theory, known as the Oppenheim Conjecture.

Relation Between Mean Proportionals of Parts and the Whole of a Line Segment

Authors: Radhakrishnamurty Padyala
Comments: 4 Pages. 4

Galileo derived a result for the relation between the two mean proportionals of the parts and the whole of a given line segment. He derived it for the internal division of the line segment. We derive in this note, a corresponding result for the external division of a given line segment.
