🚀 Adventure 10 — L’Hôpital’s Rule (Visual)

• Why ratios like f(t)/g(t) can hide a simple long‑term truth.
• How taking derivatives can make a messy ratio become clear (visual L’Hôpital).
• How DiVA turns “limits” into something you can see.

• 🎥 Limits, L'Hôpital's rule, and epsilon‑delta definitions | Chapter 7 — Essence of calculus

Watch how complicated curves can be rebuilt using simple pieces like lines and parabolas. You’ll see how zooming in lets you approximate almost anything—and why those approximations keep getting better.

• 📖 “The Feynman–Gamow Deep‑Space Mission”

Read or listen to the story of a daring space mission where the crew must use L’Hôpital’s Rule to navigate through a cosmic storm. Experience the tension and triumph as they apply mathematical insights to save the day!

• ✏️ Open: Adventure 10 — Activity Page

Complete the interactive activity to explore L’Hôpital’s Rule in action. Build your own approximations and see how close you can get. Each step adds more accuracy—can you tell when your model is “good enough”?

• ✏️ Open: Buffon’s Needle Problem

Explore the classic Buffon’s Needle Problem and its connection to estimating π through probability and geometry. Drop a needle at random and see what happens—you can actually estimate π from pure chance. It’s a surprising way to see how randomness and geometry connect.
