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 Iā€™d recommend it. Just define the equation you have here and do structural_simplify to generate the extended form.
