Limits & Continuity
Big idea: a function can aim squarely at a value it never reaches — and the limit, the bedrock of all of calculus, captures exactly where it is headed.
Topics
Limits, graphically & numerically — one-sided and two-sided limits, and when a limit fails to exist.
Evaluating limits — the limit laws, algebraic techniques, the Squeeze Theorem, and limits at infinity.
Continuity — the three-part definition, classifying discontinuities, and the Intermediate Value Theorem.
You'll be able to…
- Estimate a limit from a graph or a table of values.
- Evaluate limits with the limit laws and resolve \(\tfrac{0}{0}\) forms by factoring or rationalizing.
- Test continuity at a point with the three-part definition and classify any break.
- Find horizontal asymptotes by evaluating limits at \(\pm\infty\).
