Hi,
I can only solve second order differential equations with ODEProblem. I would like to know how to define higher order differential equations.
dddx+0.12ddx+39.48dx+4.73741*x=4.73741

Higher order diffeqs can always be written as 1st order by introducing more variables.

And ModelingToolkit.jl can automate this transformation, so I’d recommend it. Just define the equation you have here and do structural_simplify to generate the extended form.
