Differential Equations: Page 19 4 Continuous dynamical systems: coupled first order differential equations We focus on systems with two dependent variables so that dx 1 dt = f(x 1,x 2,t) and dx 2 dt = g(x 1,x 2,t). Most of the analysis will be for autonomous systems so that dx 1 dt = f(x 1,x 2) and dx 2 dt = g(x 1,x 2). (1) A useful compact ...

Solve a system of several ordinary differential equations in several variables by using the dsolve function, with or without initial conditions. To solve a single differential equation, see Solve Differential Equation.

When physical phenomena are modeled with non-linear equations, they are generally approximated by linear differential equations for an easier solution.

How do we solve coupled linear ordinary differential equations? Use elimination to convert the system to a single second order differential equation. Another initial condition is worked out, since we need 2 initial conditions to solve a second order problem. Solve this equation and find the solution for one of the dependent variables (i.e. y or x).
