To change the graph paper to a polar grid, start by clicking on the wrench in the upper right hand corner of the graph paper to open the Graph Settings menu.
To graph in polar form, write your equation using r and theta notation:
Polar graphs are automatically set to a domain of [0,12pi]. It's possible to restrict this domain using restrictions. However, it's not currently possible to use a larger domain.
Currently, graphing polar coordinates isn't supported - but it's on our list! You can find more helpful example graphs by clicking on the three horizontal lines in the upper left hand corner of the calculator.
