In computer science often the "runtime" of an algorithm can be described with a recurrence relation, here is an example:
where
If you let
then
so
Idealy I could write in terms of somehow then use partial fractions and find the appropriate taylor series to solve this. The problem is I don't know how to proceed, how to write in terms of . Has anyone ever come across this before?
