I wanted to avoid doing to many computations to create a polar graph because my strategy of crowd sourcing points does not work as well over Zoom as in the classroom. So, together as a class we found a few points on r = 1 – 2sin(theta).

Then we made Desmos find and plot the other points one at a a time. Desmos like to plot table points in the rectangular system so I developed this work around.

Define a function, maybe called r_{1} that represents your polar function.

Make a table for r_{1} and add points to it as a class. Watch the points plot. (See below for how to do that)

On a new line have Desmos use your table results to plot the table points in polar coordinates. Make sure you use the function name and independent variable name from your table.

If you want to graph the function later you need to use r = … If you graph the function you used to create your table it will be graphed as though it were a rectangular function.
