    I know how to use 0 < |x−a| < δ ⇒|f(x)−L| < ɛ when "a" is some fixed real number, but what do we do when "a" = ∞? Can we still use the definition 0 < |x−a| < δ ⇒|f(x)−L| < ɛ?

    As is often the case with technical subjects we are presented with an unfortunate choice: an explanation that is accurate but incomprehensible, or comprehensible but wrong.
