Graphing Calculator

What is Graphing Calculator?

Graphing Calculator plots mathematical functions interactively. Enter equations like y=sin(x), y=x²+3, or y=log(x) and see them rendered on a coordinate grid with zoom, pan, and multiple function overlays.

How to use

1. Step 1 — Type a mathematical expression (e.g. sin(x), x^2, log(x)) into the equation input field.
2. Step 2 — Click Plot to render the function. Add more equations to overlay multiple curves with different colors.
3. Step 3 — Zoom and pan to explore the graph. Export the plot as a PNG image for homework or reports.

Result

A student plots y=sin(x) and y=cos(x) together to visualize their phase relationship, then zooms in near x=π/4 to find the intersection point at (π/4, √2/2).
