I have the following code in maxima to calculate the laplacian of a function in parabolic coordinates.

assume(r≥0)$

assume(theta≥0,theta≤2*π)$

load(vect)$

derivabbrev:true$

scalefactors(parabolic)$

declare(f,scalar)$

depends(f,rest(parabolic))$

ev(express(laplacian(f)),diff,expand,factor);

What is the proper way to run those Maxima commands in SageMath?

Thanks,

Daniel
