Non-Linear Systems of ODEs

A slecture by Yijia Wen

6.0 Concept

Consider the system of ODEs in 4.0,

$ \frac{dx_1}{dt}=f_1(t,x_1,x_2,...x_n) $

$ \frac{dx_2}{dt}=f_2(t,x_1,x_2,...x_n) $

...

$ \frac{dx_n}{dt}=f_n(t,x_1,x_2,...x_n) $

When the $ n $ ODEs are not all linear, this is a nonlinear system of ODE. In this tutorial, we will see nonlinear systems in different aspects to build up a basic completed concept.
