Frequently Asked Questions
How does the Graphing Calculator work?
The tool parses your math expression into an abstract syntax tree, then evaluates it for hundreds of x-values across the visible viewport. Each (x, y) pair is mapped to canvas pixel coordinates using the current zoom and pan offsets, and connected with line segments to draw a smooth curve. Panning and zooming recalculate the viewport bounds and re-evaluate the function across the new range.
What math functions can I graph?
Any function of x, including polynomials, trigonometric functions (sin, cos, tan), logarithms, square roots, absolute value, and combinations of these. You can plot multiple functions simultaneously.
Can I zoom and pan the graph?
Yes. Use the zoom controls or scroll to zoom in and out, and drag to pan across the coordinate plane. You can also trace along the curve to see exact coordinates at any point.
How is this different from a TI-84?
It provides a similar graphing experience in your browser with no hardware needed. You can enter functions, adjust the viewing window, and trace values just like a physical graphing calculator.
