ABSTRACT
We will be dealing with a system of first-order ordinary differential equations solved for the derivatives y k ′ = f k ( x , y 1 , … , y n ) , k = 1 , . . . , n . $$ y^{\prime}_{k} = f_{k} (x,~y_{1} ,~ \ldots ,~y_{n} ),\,\,k = 1,...,n. $$ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315117638/585bf32b-5ab3-4664-8be7-28e9abefef4b/content/math7_1.tif"/>
