Polar Graphing Calculator

Graph a polar equation by entering a radius r as a function of angle θ. Choose degrees or radians, adjust the angle interval and sample count, then inspect the curve and download its coordinates.

Use θ or t as the angle variable. Trigonometric functions follow the chosen angle unit. Supported functions: sin, cos, tan, sqrt, abs, exp, ln and log. Numerical samples may miss discontinuities; this is not symbolic proof. Runs locally; no upload.

How do you graph a polar equation?

Enter a radius expression such as 1 or 2*cos(θ), choose an angle interval and unit, then calculate. The graph converts each sampled polar point to x=r cos(θ) and y=r sin(θ). For r=1 from 0° to 360°, the result is the unit circle.

Frequently asked questions

How do you graph a polar equation?

Enter a radius expression such as 1 or 2*cos(θ), choose an angle interval and unit, then calculate. The graph converts each sampled polar point to x=r cos(θ) and y=r sin(θ). For r=1 from 0° to 360°, the result is the unit circle.

Is my equation uploaded?

No. The equation is parsed and plotted locally in this browser. It is not uploaded or saved by this tool.

What does r=1 look like in polar coordinates?

Every angle is one unit from the origin, so r=1 forms a circle of radius 1 centered at the origin.

Can I export polar graph points?

Yes. After plotting, download a CSV containing each finite sampled angle, radius and its Cartesian x and y coordinates.
