About this project

We built one dashboard for a classic calculus prep task: find Δf / Δx fast, on any screen.

Average Rate of Change Calculator uses a dark, edge-lit layout inspired by live sports stats panels so numbers stay readable under bright or dim lighting.

The site is fully static: HTML, Tailwind, and a small Alpine.js module. That keeps Cloudflare Pages deployment simple and your inputs on your device.

Copy lives in JSON so guides and labels can evolve without hunting through templates.

2 to 10 configurable (x, f(x)) rows
Live formula line that updates with your point count
Mobile-first controls with strong contrast on buttons and links
