Graphing Calculator — plot functions and equations

What this tool does

This Graphing Calculator (Function Plotter) lets you plot common math graphs directly in your browser:

• Function graphs: (y = f(x))
• Parametric curves: (x(t), y(t))
• Implicit equations: (F(x,y)=0)
• Inequalities: (F(x,y) < 0), (<= 0), (> 0), (>= 0)

Examples

Function

• sin(x)
• x^2 - 4
• x < 0 ? -x : x (piecewise via ternary)
• |x| (absolute value)

Parametric

• x(t) = cos(t), y(t) = sin(t) (circle)

Implicit

• x^2 + y^2 - 1 = 0 (circle)

Inequality

• x^2 + y^2 - 1 < 0 (inside the unit circle)

Export

Use Export SVG for a vector graph (best for editing and printing), or Export PNG for a bitmap image.
