In addition, we also determined inequalities for special cases of our results and provided examples of these cases with their graphical representations.en10.1186/s13661-025-02040-8info:eu-repo/semantics/openAccessSimpson's type inequalityIntegral inequalitiesGeneralized fractional integralsBounded second derivativesArticle202512-s2.0-105001523080WOS:001458906400001Q1Q1
