In this article, we study an approximation of a system of differential equations when it has a noise. We use the Taylor method and we model the organization of such systems. In a system of differential equations, we set a scalar multiplication with a function and we saw that this system can be in chaotic mode. We used a method to omit the noises and chaos in this system.
