Separation of variables
Posted:
May 14, 2008 5:00 PM


If solving a PDE using separation of variables, let's say the poisson equation, then it becomes x"/x+y"/y=0
That gets that x"/x=constant and likewise for y.
Now let's say after separation of variables of some problem I have x"/x+y"/y+yz"/z=0
Would I be able to say that x"/x=constant?
