Calc 1: Differential Calculus

Lecture 24: Techniques for Sketching Graphs

---

This video is about sketching the graph of a function. We talk about limits at infinity and asymptotes, but it is primarily in aid of graphing. We stick primarily to rational functions in this video, because it is already a pretty long video. It's only long because I wanted to do as many examples as I could!

Note: In this video we talk about "limits at infinity". There is a way to formally define the concept, but we do not give the formal definition of a limit at infinity here. For our purposes, the informal and intuitive idea of "things getting bigger" is enough for us.
