What is a Graphing Calculator?

A graphing calculator is a tool that plots mathematical functions on a 2D graph, helping you visualize equations like y = x² or y = sin(x). It’s widely used in algebra, calculus, and physics to study function behavior, intersections, and trends. Our free online graphing calculator makes plotting easy with zoom and pan features.

Key Features of Our Calculator

• Function Plotting: Graph up to two functions at once, such as polynomials (x^2), trigonometric (sin(x)), or exponentials (e^x).
• Zoom and Pan: Use the mouse wheel to zoom in/out and drag to pan the graph for detailed exploration.
• Custom Range: Adjust x and y axis limits to focus on specific graph areas.
• Supported Functions: Includes sin, cos, tan, exp, ln, sqrt, and basic operations (+, -, *, /, ^).

How to Use the Calculator

Enter a function and click Plot to see the graph:

• Enter Functions: Type equations like x^2 or 2*x + 3. Use a second function for comparison (e.g., cos(x)).
• Adjust Range: Set x-min, x-max, y-min, and y-max to zoom in or out (e.g., -5 to 5 for x).
• Interact: Scroll to zoom, click and drag to pan the graph.
• Reset: Click Reset to clear inputs and restore default view.
