Lesson 6: Continuity II, Infinite Limits

The document is a lesson on continuity and infinite limits. It defines infinite limits, including limits approaching positive or negative infinity. It provides examples of evaluating limits at points where a function is not continuous. It also outlines several rules of thumb for manipulating infinite limits, such as the sum or product of an infinite limit with a finite limit being infinite. The document cautions that limits of indeterminate forms like 0×∞ or ∞-∞ require closer examination rather than following rules of thumb. It provides an example of rationalizing an expression to put it in a form where limit laws can be applied.
