Learning Objectives

By the end of this module, you will be able to:

  • Explain the intuitive concept of a limit using tables and graphs
  • Evaluate limits algebraically using direct substitution, factoring, and rationalization
  • Determine limits at infinity and identify horizontal and vertical asymptotes
  • Define continuity at a point and on an interval
  • Apply the Intermediate Value Theorem to locate roots of equations

Module Lessons

1

The Intuitive Idea of a Limit

Explore what it means for a function to approach a value. Use tables, graphs, and one-sided limits to build intuition.

30-40 minutes

2

Computing Limits Algebraically

Master the algebraic techniques: direct substitution, factoring, rationalization, and limit laws.

35-45 minutes

3

Limits at Infinity and Asymptotes

Investigate end behavior, horizontal asymptotes, and infinite limits that produce vertical asymptotes.

30-40 minutes

4

Continuity and the Intermediate Value Theorem

Learn the formal definition of continuity, identify types of discontinuities, and apply the IVT.
