In this lesson I introduce the concept of limits of functions (so far we dealt only with sequence limits). I show what is new and review the methods you already know – all of which can still be used for functions.

Note: Although the title says “simple”, the simplest function-limit problems can turn out to be the hardest – and I’ll show you how to defend yourself against that.
