Abstract: In this paper, based on Riemann-Stieltjes integral, we study a new type of derivative. Some important properties of this new type of derivative is obtained, including derivative of inverse function, first derivative test, second derivative test, test of concavity, and L'Hôpital's rule. In fact, our results are generalizations of the results in classical differential calculus.
Keywords: Riemann-Stieltjes integral, new type of derivative, derivative of inverse function, first derivative test, second derivative test, test of concavity, L'Hôpital's rule.
