Most phenomena can be modeled not by single differential equations, but by systems of interacting differential equations. These systems may consist of many equations. of the system, emphasizing that the system of equations is a model of the physical behavior of the objects of the simulation. In general the stability analysis depends greatly on the form of the function f(t;x) and may be intractable.

Typically a complex system will have several differential equations. The equations are said to be "coupled" if output variables (e.g., position or voltage) appear in more than one equation. Two examples follow, one of a mechanical system, and one of an electrical system.

A system of equations is a set of one or more equations involving a number of variables. The solutions to systems of equations are the variable mappings such that all component equations are satisfied—in other words, the locations at which all of these equations intersect. Rewriting Scalar Differential Equations as Systems In this chapter we’ll refer to differential equations involving only one unknown function as scalar differential equations. Scalar differential equations can be rewritten as systems of first order equations by the method illustrated in …

Differential equation or system of equations, specified as a symbolic equation or a vector of symbolic equations. Specify a differential equation by using the == operator. If eqn is a symbolic expression (without the right side), the solver assumes that the right side is 0, and solves the equation eqn == 0.. In the equation, represent differentiation by using diff.

The package systeme can also be used, which I guess the other answer might use. I would strongly recommend you formating your code better. I've been working with sympy and scipy, but can't find or figure out how to solve a system of coupled differential equations (non-linear, first-order). So is there any way to solve coupled differ The system of PDEs above can be solved using the procedure described in Chapter V, Sec IV of Goursat's Differential Equations. The first step is to find the complete, non-commutative group of differential operators that includes equ5 and equ6. comm[equa_, equb_] := Collect[(equa /.
