Polar Curve Plotter. To sketch a polar curve, first step is to sketch the graph of r=f (θ) as if they are x,y variables. This will give a way to visualize how r changes with θ. The information about how r changes with θ can then be used to sketch the graph of the equation in the cartesian plane.
In the rectangular coordinate system, we can graph a function \(y=f(x)\) and create a curve in the Cartesian plane. In a similar fashion, we can graph a curve that is generated by a function \(r=f( \theta )\). The general idea behind graphing a function in polar coordinates is the same as graphing a function in rectangular coordinates.
A polar curve is simply the resulting graph of a polar equation defined by r and θ. We use polar grids or polar planes to plot the polar curve and this graph is defined by all sets of (r, θ), that satisfy the given polar equation, r = f (θ).
There are five classic polar curves: cardioids, limaҫons, lemniscates, rose curves, and Archimedes’ spirals. We will briefly touch on the polar formulas for the circle before moving on to the classic curves and their variations.

To visualize how polar curves are drawn, this plotter utilizes a unique animation method showing the polar graph's step-by-step construction. You can pause, resume, and control the speed of polar plotting process with the provided slider.
Polar Curves. Now that we know how to plot points in the polar coordinate system, we can discuss how to plot curves. In the rectangular coordinate system, we can graph a function y = f (x) y = f (x) and create a curve in the Cartesian plane. In a similar fashion, we can graph a curve that is generated by a function r = f (θ). r = f (θ).
A polar curve is a shape constructed using the polar coordinate system. Polar curves are defined by points that are a variable distance from the origin (the pole) depending on the angle measured off the positive x x -axis.
