Fuzzy Calculus with a Novel Approach Using Fuzzy Functions

This article deals with the complexity involved in fuzzy derivatives when both input and output are from nonempty, convex, and compact fuzzy space. Consider a fuzzy valued mapping, and for fuzzy differentiation of fuzzy valued function, we propose Modified Hukuhara derivative. To evaluate this derivative, we need to take the parametric form of, input and the mapping which is involved in it. Our definition gives a more realistic explanation of fuzzy derivatives, under this derivative, we also develop fuzzy Taylor series along with its convergence. Lastly, we solve a fully fuzzy differential equation with initial condition using Fuzzy Taylor series.
