We prove two Hermite-Hadamard type inequalities for the newly introduced class of functions. We also obtain some refinements of the Hermite-Hadamard inequality for functions whose first derivative in absolute value, raised to a certain power which is greater than one, respectively at least one, is harmonic trigonometrically convex.eninfo:eu-repo/semantics/openAccessConvex functiontrigonometrically convex functionharmonic trigonometrically convexityHermite-Hadamard in-equalityArticle37238029803810.2298/FIL2323029K2-s2.0-85162834024Q3WOS:001011537400001Q2
