For that, I would look at early calculus/pre-calc, I think, examining infinite series and their properties and equivalencies.
There's certain forms like that that have well known values that they converge to as you continue adding terms into infinity. Sometimes that convergence is only possible if your domain is limited, eg. [0,1].
