• Oppeheim's problem
• Shafer inequality
• Fink inequality
• Malesevic inequality

In this paper, the open problem proposed by Oppeheim [A. Oppeheim, E1277, The American Mathematical Monthly, 64, (1957) p. 504] is discussed carefully. At the same time, the Shafer, Fink and Malesevic inequalities are deduced from the solution of Oppeheim's problem.
