NOT BASEBALL
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 r1 that represents your polar function.
- Make a table for r1 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.
