Sketch the graph of the curve whose equation in polar coordinates is \(r=3\cos 3\theta\text{.}\) Sketch the curve whose polar equation is \(r=-1+\cos \theta\text{,}\) indicating any symmetries. Mark ...

Here is another applet in which you can plot polar curves . Polar Curves Plotter: 10.3: Just a polar curve grapher. Type in your polar equation and investigate the graph. Polar Curves and Cartesian ...

Actually, there’s a much simpler way to use polar coordinates. Back in the 30’s and 40’s, my sister and I had a “Hootnanny. See the page here: ...

Based on polar coordinate, the BUAA researchers developed a printing setup with a rotating mandrel as the substrate, called Polar-coordinate Line-projection Light-curing Production (PLLP) technology.
