Regarding the initial conditions in multiplication and addition when they are not at the same point:
I think the best is(already discussed at ideas page) first to check if both the given holonomic functions are elementary function and calculate the initial conditions at a same point symbolically, where both the functions doesn't have a pole. So for the resulting function the initial condition would be addition/multiplication of calculated conditions at that point. In case when one or both can't be converted to elementary we will calculate numerical value at a point and add/multiply them. How are we gonna do this in INTEGRATION and DIFFERENTIATION? In application with a algebraic function, let's say we have initial condition at x0, then if it's possible we can get the point where the algebraic function is equals to x0, let it be x1 ,and now we have the initial condition of resulting function at the point x1. For derivatives we will multiply the given initial condition with the corresponding derivative of algebraic function at x1. Is this method suitable enough? I'd appreciate to know your views on it.
