The Derivative Formula Explained: From Secant Lines to Tangent Lines

How do you find the slope at a single point when slope requires two points? This video reveals the elegant solution: start with two points, then use limits to bring them infinitely close together. You'll see exactly how the difference quotient transforms into the derivative formula. 📚 Key concepts covered: • The difference quotient [f(x₀ + h) - f(x₀)] / h as the slope of a secant line • Why we can't just plug in h = 0 (the 0/0 problem) • How limits let us approach zero without reaching it • The geometric meaning: secant lines rotating into tangent lines • Complete worked example with y = x² at x = 3 ━━━━━━━━━━━━━━━━━━━━━━━━ 📖 ORIGINAL SOURCE ━━━━━━━━━━━━━━━━━━━━━━━━ This video distills concepts from:    • Calculus 1 Lecture 1.5:  Slope of a Curve,...   Full credit to the original creator.
