I wouldn't even dream of typing out all $40$ equations I ended up graphing, but here's the final result, which looks considerably nicer than what I started with:Īnd here's the link to the final version, in case anyone's curious. Feel free to post demonstrations of interesting mathematical phenomena, questions about what is happening in a graph, or just cool things youve found while playing with the graphing program. To obtain the center and the first two petals, and the result looked exactly like what I had hoped for: A subreddit dedicated to sharing graphs created using the Desmos graphing calculator. I thought that was a clever idea, so I started with the equation of an ellipse in rectangular coordinates in complete generality and set to work converting that to polar coordinates: (Pull off the last page and use the polar grids. I found that Desmos Graphical Calculator handles various equations and. When you visit your Google Drive dashboard, you will find your graph present there in the PDF file format. Simply select a file name and click on the ‘Save Graph’ button. The information about how r changes with can then be used to sketch the graph of the equation in the polar coordinate system. When you are done with your graph plots, you can save them directly to your Google Drive account. This will give a way to visualize how r changes with. The online graphing sites give you the basic shapes, but you must label points and other features of the graphs. To sketch the graph of a polar equation a good first step is to sketch the graph in the Cartesian coordinate system. Remember, you must draw the graphs by hand. The OP mentions in a comment the idea of graphing individual ellipses to match the shape and position of each petal. Question: Polar Equations You can use Desmos Polar Grapher. In attempting to answer this interesting but abandoned question, I ran into a strange problem that I've never seen before and have no idea how to resolve.įor some context, the question contains a picture of a flower and asks how one would go about precisely plotting the flower in polar coordinates.
