I'm trying to do some symbolic calculus and am having trouble with the special function spherical_bessel_J(). I can't get it to work when the argument contains two factors.
Here is a simple program:
k=var('k');
k=maxima(k);
rho=var('rho');
rho=maxima(rho);
arg=var('arg');
arg=maxima(arg);
arg=k*r
I want to use MAXIMA to perform the separation of variables on a 3d nonlinear differential equation (and then solve a 1d equation). I think I can write a program to do this by trial and error with different functional forms, but I'm new to SAGE and don't want to start from scratch. Can you think
