Convert the following into a system of 1st order DEs:
y'' + 2xy' + (y^2)Sin(x) = e^x y(0) = 1 y'(0) = 2 KTHANX

We are not gonna do your damn ODE homework.
Do you have a specific question about a technique to use? |

ok, i see that this is a nonlinear equation.
that is where i'm hung up. Honestly, any direction would be grand |

I wish I had GD back then. ODEs are hard as shit.

1) Assign state variables
2) Make state equations 3) Put into state space form and include output equation |

Horse shit. I knew none of you all could solve this shit. It's cause you're full of shit.
Or else, not enough time has elapsed yet. |

Laplace or change of variables?
Been awhile since I have done one of those. |

I told you how to do it why have you not figured it out? I will give you another clue. It is a method used in controls and it only takes simple algebra manipulation to create the equations. |
