Ini tially, we establish a novel identity using the two-point Newton Cotes formula for multiplicatively differentiable functions. Using this identity, we derive Companion of Ostrowski’s inequalities for multiplicatively differentiable convex mappings. The work also pro vides the results’ applications.enNon-Newtonian calculus, Companion of Ostrowski inequalityMultiplicatively convex functions.Companion of Ostrowski Inequality for Multiplicatively Convex FunctionsArticle
