An Inquiry-Based Approach to Real Analysis

We will not be using a traditional textbook this semester, but rather a problem sequence adopted for an inquiry-based learning (IBL) approach to real analysis. The problem sequence that we are using is an adaptation of the analysis notes by Karl-Dieter Crisman, which are a modified version of notes by W. Ted Mahavier. Both authors have been gracious enough to grant me access to the source of these notes, so that we can modify and tweak for our needs if necessary. The notes will be released incrementally. Each link below is to a PDF file.

• Title Page and Front Matter
• Preface
• Chapter 1: Introduction
  • 1.1 What is This Course All About?
  • 1.2 An Inquiry-Based Approach
  • 1.3 Rights of the Learner
  • 1.4 Your Toolbox, Questions, and Observations
  • 1.5 Rules of the Game
  • 1.6 Structure of the Notes
  • 1.7 Some Minimal Guidance
• Chapter 2: Preliminaries
  • 2.1 Basics
  • 2.2 Logic Review
  • 2.3 Sets and Functions
  • 2.4 Order Properties of the Real Numbers
• Chapter 3: Point Sets and Sequences
• Chapter 4: Standard Topology of the Real Line
• Chapter 5: Continuity
• Chapter 6: Differentiation
• Chapter 7: Integration
• Appendix A: Elements of Style for Proofs
• Appendix B: Fancy Mathematical Terms
• Appendix C: Definitions in Mathematics

I will not be covering every detail of the notes and the only way to achieve a sufficient understanding of the material is to be digesting the reading in a meaningful way. You should be seeking clarification about the content of the notes whenever necessary by asking questions. Here’s one of my favorite quotes about reading mathematics.

Don’t just read it; fight it! Ask your own questions, look for your own examples, discover your own proofs. Is the hypothesis necessary? Is the converse true? What happens in the classical special case? What about the degenerate cases? Where does the proof use the hypothesis?
