Introduction to Limits 2, Limits, Precalculus

Sal explains limits by looking at a basic example of a discontinuous function and takes a more intuitive point of view before looking at a formal mathematical definition in later videos. He starts by introducing the notation for limits and describes some of the reasoning that goes into understanding limits. This video covers the same material as the video titled "Introduction to Limits (HD).” It is four minutes shorter and contains one fewer example.
