I have a function of two variables $f(r,x,c)$, where $r$ and $x$ are variables and $c$ is a constant that appears in the function.
I would like to write it as a product of two functions $f1(r,c) \times f2(x,c)$.
If I set
c = 1 and use
FullSimplify, it automatically gives me the function in the form
f1[r]*f2[x]. However, if no assumptions about
c are provided
FullSimplify doesn't work.
(Based on the Physics problem I am trying to solve there are reasons to believe that I should be able to write down function in the form $f(r,x,c)=f1(r,c) \times f2(x,c)$ )
Is there any command or procedure in Mathematica to separate the functional dependence of a given function with two variables?
