What Is This?
A fully functional graphing calculator that lives in your browser — no apps to install, no accounts to create. It looks, sounds, and feels like the real thing sitting on your desk.
Why Does It Exist?
Because calculators shouldn't require a download, and math shouldn't feel boring. This was built as a love letter to the classic graphing calculators that got us through school — reimagined for the web.
Who Is It For?
Students, makers, tinkerers, the casually curious, and anyone who appreciates a well-crafted tool. Whether you're splitting a dinner bill or graphing SIN(X), this has you covered.
How to Use It
Calc mode: Type expressions and press ENTER to evaluate. Use the conversion buttons (TIP, F→C, in→cm) for everyday math.
Graph mode: Switch to Graph, type a function using X as the variable (like SIN(X) or X^2), and press ENTER to plot it.
Random: Hit the Random button to see example formulas and graphs in action.
Drag: Grab the calculator body and move it anywhere on the desk.
2nd key: Access inverse trig functions (sin⁻¹, cos⁻¹, tan⁻¹) and alternate conversions.
Keyboard: Numbers, operators (+−*/^%), Enter, Backspace, arrows, and parentheses all work. Letters map to functions: S=sin, C=cos, T=tan, L=ln, R=√, P=π, N=±, A=ans.
