The Narrative Structure
This unit moved you through the full intellectual arc of calculus:
- 1.Concrete problems of tangents and velocity
- 2.Procedural toolkit of algebraic limits
- 3.Profound implications of continuity and infinite behavior
- 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.
