Solving a system of differential equations is somewhat different than solving a single ordinary differential equation. The solution procedure requires a little bit of advance planning. The system of differential equations must first be placed into the "standard form" shown The techniques for solving differential equations based on numerical approximations were developed before programmable computers existed. During World War II, it was common to ﬁnd rooms of people (usually women) working on mechanical calculators to numerically solve systems of differential equations for military calculations.

I've found other questions on systems of nonlinear equations asked in MatLab answers and have managed to produce a plot for my own system, but this plot is not the same as the one in the paper I'm using.

It is not uncommon for a problem to be difficult to solve numerially, although it looks like a rather simple system of differential equations. There are several reasons for that, but the "usual The Wolfram Language's differential equation solving functions can be applied to many different classes of differential equations, automatically selecting the appropriate algorithms without needing preprocessing by the user.

Most phenomena can be modeled not by single differential equations, but by systems of interacting differential equations. These systems may consist of many equations.

In this section we consider the different types of systems of ordinary differential equations, methods of their solving, and some applications to physics, engineering and economics. Linear Homogeneous Systems of Differential Equations with Constant Coefficients You can directly solve this system with DSolve, if you split it into two steps, since v-equation can be solved separately.

Differential Equation Calculator. The calculator will find the solution of the given ODE: first-order, second-order, nth-order, separable, linear, exact, Bernoulli, homogeneous, or inhomogeneous. Initial conditions are also supported. You can directly solve this system with DSolve, if you split it into two steps, since v-equation can be solved separately.
