Abstract :
In this work, a basic theorem is established and it is found to be a source of inequalities
for circular functions, such as Cusaʹs, Huygensʹ, Wilkerʹs, the Sandor Bencze, Carlsonʹs,
the Shafer Fink inequality, and the one in the problem of Oppenheim. Furthermore, these
inequalities described above will be extended by this basic theorem.
