Function Graph Calculator
Enter a formula to draw its graph. Supports trigonometric, exponential, and logarithmic functions, plus polar and parametric curves.

Available: + - * / ^, sin cos tan asin acos atan, sinh cosh tanh, ln log log2 exp sqrt cbrt abs floor ceil mod, constants pi(π)·e. Trig functions use radians. (e.g. multiplication can be omitted, like 2x or 3sin(x))

The function graph calculator plots your equation in real time. It supports linear and quadratic functions, trigonometric, exponential, and logarithmic functions, and even polar and parametric curves.
Supported graph types
It supports three modes: standard Cartesian functions of the form y=f(x), polar functions r=f(θ), and parametric curves (x(t), y(t)) — covering even advanced-level curves.
Frequently Asked Questions
What syntax should I use for functions?
Standard math notation works — sin, cos, tan, log, ln, sqrt, exp, and operators +, -, *, /, ^.
Can I zoom in and out of the graph?
Yes, use the mouse scroll wheel or the zoom buttons to freely adjust the view.
Can I plot multiple functions at once?
Yes, you can add several equations and compare them simultaneously on the same coordinate plane.
How are undefined regions shown?
Regions where a value is undefined — like the negative domain of a logarithm — are simply broken or omitted from the graph.
