What this tool shows
This project focuses on building intuition for two core ideas in calculus:
Derivatives: how local slope changes as you move along a curve,
visualized using a tangent line that updates in real time.
Integrals: how area accumulates under a curve, shown through
shaded regions and numerical approximation.
Why this matters
Instead of presenting formulas first, the tool emphasizes visual cause-and-effect: how a small change in x affects y, and how many small contributions build up into a total quantity.
