Equation Types
Explicit Functions
Functions with one variable isolated
y = x^2y = sin(x)x = y^2 + 1Implicit Equations
Equations with both variables
x^2 + y^2 = 25x^2 - y^2 = 1Inequalities
Use >, <, >=, <= for shaded regions
y > x^2y <= sin(x)Polar Coordinates
Use r and theta variables
r = sin(theta)r = 1 + cos(theta)Tips & Shortcuts
- Press Ctrl+Z to undo, Ctrl+Y to redo
- Drag on the graph to pan, scroll to zoom
- Paste multiple equations (one per line) to add them all at once
- Click the color box to cycle through colors
- Use the toggle buttons to show/hide lines, points, or make lines dashed
- Invalid equations will show a red error message
