Graphing Calculator: 2D Function Plotter & Coordinate Analysis
The Compute Lab Graphing Calculator plots algebraic, trigonometric, exponential, and rational mathematical equations dynamically onto a responsive 2D Cartesian coordinate plane. Explore function roots, local extrema, asymptotic limits, and multi-curve intersections with real-time panning and smooth zooming.
How to Plot and Analyze Equations
Enter Equations
Type mathematical formulas into the input list. Type x^2 - 4 or sin(x). The engine parses explicit formulas or "y =" expressions automatically.
Pan & Zoom Canvas
Click and drag anywhere on the grid to pan your perspective. Use your mouse scroll wheel or on-screen zoom buttons to inspect macroscopic trends or microscopic roots.
Compare Functions
Add multiple functions using the "+" button. Each function is highlighted in a distinct color, making visual comparison of intersections and offsets effortless.
Curated Function Patterns to Try
y = x^2 - 4*x + 3Notice vertex at (2, -1) and x-intercepts at x = 1 and x = 3.y = 2 * sin(3*x)Amplitude of 2 with frequency multiplier 3, oscillating periodically across the x-axis.y = 1 / (x - 2)Displays a vertical asymptote at x = 2 with hyperbola arms approaching ±infinity.y = 2^xRapid upward trajectory crossing y-intercept at (0, 1) and approaching y = 0 as x → -∞.Graphing Calculator FAQs
How does the rendering engine achieve smooth 60fps interaction?
The canvas utilizes high-performance HTML5 2D Canvas rendering with debounced coordinates calculation. When dragging or resizing, math expressions are sampled across the horizontal pixel width, calculating corresponding y-coordinates instantly without external API overhead.
