Package like odepack needs the ODE written in standard form, which means write the high order ODE to first order ODE equations. The steps of converting ODE to standard form are quite standard, but I do not find functions in Mathematica that can rewrite high order ODE into its standard form. For example, EQ = y''[x] + Sin[y[x]] y[x] == 0

In mathematical analysis, Clairaut's equation (or the Clairaut equation) is a differential equation of the form = + ()where f is continuously differentiable.It is a particular case of the Lagrange differential equation. It is named after the French mathematician Alexis Clairaut, who introduced it in 1734.

d2x(t) dt2 ··· dnx(t) dtn = g(t). (5.1). These differential equations are identified according to 5,  2 x2 + C, where C is an arbitrary constant—the constant of integration. This is the general solution of the ODE. More generally, ODEs of the form dy dx. = f(x)g(y),.

This is somewhat reminiscent of the power rule. The equation of family of standard circle with radius r is x 2 + y 2 = r 2, where r is an arbitrary constant. Differentiating w.r.t. x, we get `2x + 2y ("d"y)/("d"x)` = 0 ∴ `x + y ("d"y)/("d"x)` = 0 Standard and Differential Form of First-Order Differential Equations - YouTube.

And elliptic equations are associated to a special state of a system, in principle corresponding to the minimum of the energy. Mathematically, these classification of second-order PDEs is based upon the possibility of reducing equation (2) by coordinate transformation to canonical or standard form at a 2013-08-15 · Fundamentals of Differential Equations and Boundary Value Problems, by Nagle, Saff, and Snider, Addison-Wesley.

= 1. This gives a differential equation in x and z that is linear, and can be solved using the integrating factor method. Note: Dividing the above standard form by yn gives   a single high-order differential equation is introduced. If differential equations can be successfully converted into the standard form, solvers such as ode45() can  We can ask the same questions of second order linear differential equations.
