In this paper, a new class of convex functions, which is called exponential trigonometric con-vex functions is studied. We obtain some refinements of the Hermite-Hadamard type inequal-ities via functions whose second derivatives in absolute value at certain power are exponential trigonometric convex functions. The results of the research by the means of Holder-Iscan and improved-power-mean integral inequalities.
