when 2, p = the p − functions sin p , cos p , tan p become our familiar trigonometric functions. Recently, the generalized trigonometric functions have been studied by many mathematicians from different viewpoints(see [2,4,5,6,7]). In [5,9], the authors gave basic properties of the generalized trigonometric functions. In [6], Klen, Vuorinen and Zhang generalized some classical inequalities for trigonometric functions, such as Mitrinovic-Adamovic’s inequality, Lazarevic’s inequality, Huygens-type inequalities, and Wilker-type inequalities, to the case of generalized functions. 3rd International Conference on Mechatronics and Information Technology (ICMIT 2016)
