Polar Curves and Cartesian Graphs. To sketch the graph of a polar equation a good first step is to sketch the graph in the Cartesian coordinate system. This will give a way to visualize how r changes ...

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 ...
