Graphing, analysis and mathematical visualization

Graph functions, analyze their behavior, and create publication-ready mathematical graphics

Work directly in the browser with a mathematical formula editor, exact-value analysis, editable objects, project files, and crisp PNG or scalable SVG exports.

Four dedicated tool pages

Choose a workspace for the result you need

Graph and analyze functions

Plot y = f(x), x = f(y), parametric and polar curves, equations, inequalities and data points; then use derivative, tangent, integral and other analysis tools.

Open tool →

Shade graph regions

Shade between two compatible graphs or on one side of a function, vertical line or coordinate axis with solid or patterned fills.

Open tool →

Create variation and derivative-analysis tables

Build a Variation Table, a First Derivative Sign Chart or a First and Second Derivative Analysis Table with exact values, concavity and inflection points.

Open tool →

Visualize solids of revolution

Rotate a region about the x-axis or y-axis, show elliptical bases and a middle cross-section, customize the illustration and calculate volume.

One workspace, many mathematics tasks

Precise input, editable output and reusable projects

The plugin combines a MathLive formula editor, exact-value verification, graph analysis, table generation, annotations and project saving. Images are selected locally and remain inside the browser project rather than being uploaded to the website.

  • Graph multiple functions, relations, parametric curves, polar curves and data points
  • Evaluate exact values, derivatives, tangents, normals, roots, extrema, integrals, areas and arc lengths
  • Generate three table types, including second-derivative concavity and inflection analysis
  • Edit text, Alpha formulas, images, lines, arrows, axes and tick marks with Undo and Redo
  • Customize bounds, grid, axis scales, labels, title, legend, colors, thickness and line styles
  • Save and reopen .ogp projects, create HTML launchers, and export PNG, SVG or Copy for Word

Recommended workflow

From formula to reusable project in four steps

1

Open the right page

Use the dedicated Graphing, Shading, Variation Table or Solid of Revolution page. The selected page opens the matching plugin tab automatically.

2

Enter formulas or data

Use the formula palette or keyboard, add functions or point data, and set the relevant interval, bounds and drawing style.

3

Analyze and customize

Run the needed calculations, adjust axes and the table type, then add editable text, formulas and images; use Line or Arrow in the modes that provide those tools.

4

Save or export

Keep the editable Functions, Table, Shading, Revolution and Axes state in an .ogp file or HTML launcher, and use PNG, SVG or Copy when the graphic is ready for a document.
