The Narrative Structure

This unit moved you through the full intellectual arc of calculus:

  1. 1.Concrete problems of tangents and velocity
  2. 2.Procedural toolkit of algebraic limits
  3. 3.Profound implications of continuity and infinite behavior
  4. 4.Rigorous foundation of the epsilon-delta definition
Final Pedagogical Insight

Frame your understanding as a historical narrative:

  • • Start with Zeno's paradoxes to create the "need" for limits
  • • Use Newton and Leibniz to show the power of the tool
  • • Use Berkeley's "ghosts" to show the logical holes
  • • Use Cauchy and Weierstrass (Epsilon-Delta) to provide the resolution

This narrative structure turns abstract mathematics into an intellectual drama, significantly improving conceptual retention.
