I think results with diff(y(x),x) are pretty useless because you can't use them in farther calculations. I hope they will implement implicit differentiation i next ROM update. Use subst() or convert the result into a string with STRING(). Then use REPLACE() and (to replace "diff(y(x),x)" with just "Yy" for example) and then convert back to a symbolic via EXPR() and continue with solving. Just make sure to add single quotes around the string before using EXPR(). You can probably automate this in a program. Graph 3D  QPI  SolveSys
