FWIW Maxima likes to see dy/dx in formulations of differential equations instead of dy(x)/dx so I think maybe this problem of whether y is a variable or a function doesn't really come into play; Maxima can always handle y as a variable. You could ask on the Maxima mailing list to see if anyone has worked with Lagrangian mechanics in Maxima. Robert Dodier
Thanks. However, It's not y(x) that's the problem, it's that the x may be a function and I need the derivative carried out. However, the code you translated should handle it. Cheers, Tim.
