Numerical Solutions of a Differential System Considering a Pure Hybrid Fuzzy Neutral Delay Theory

In this paper, we propose and derive a new system called pure hybrid fuzzy neutral delay differential equations. We apply the classical fourth-order Runge–Kutta method (RK-4) to solve proposed of ordinary First, define RK-4 for equations then establish efficiency by utilizing it particular type equation. provide numerical example verify theoretical results. addition, compare Euler solutions with exact solutions. An error analysis is conducted assess how much deviation from exactness found in two methods. arrive at same conclusion our since outperforms method.
