Understanding the Derivative: The Tangent Line Problem (Calculus Visualized)

Описание: What is a derivative? 📉 In this video, we visualize the Tangent Line Problem, the geometric foundation of Calculus.

We start by looking at the secant line and the average rate of change. By using the concept of a limit, we see how the secant line transforms into a tangent line, giving us the instantaneous rate of change. This visual explanation avoids complex proofs and focuses on the intuition behind the math.

Perfect for Calculus 1 students or anyone wanting to understand the 'why' behind the formulas! 🧠
