Systems of Nonlinear Differential Equations

  1. Sep 4, 2009 #1
    I trying to solve a system of Nonlinear Differential Equations.
    I'm using Runge-Kutta on the Differential equations and Newton Method
    for the system. I have some doubts in how to create the JAcobian to the
    differential equations.

    Could somebody help me, please?
    Thank you,

    What are the equations? Hard to help when there are no equations.

    I have in my system a equation like this:


    B and M1 are constats.

    When I apply the Runge-Kutta I have:


    My doubt is: How do I incert this in the equation of the system to build the Jacobian?

    Before discuss my question I have to learn how to post using the Latex.
    Do you know why this happened?
