To graph a unit circle on a graphing calculator {such as TlElr-l] using the typical settings. recall that you could enter y = 1.! 1 3:2. Unfortunately. this will only graph the top half of the circle. and you will also need to E, graph another function1 y = 1..! 1 3:2. [in Desmos E1. the situation is better. You can actually type in 1:2 + y = 1 to get the graph of the whole circle. {3y it nowll 55 There is another system for describing circle-based curyes: polar coordinates. In Desmos E't, type?" = 2. You should get a circle. Describe it: Q The circle is centered at the origin. with radius 4. Q The circle is centered at [2.2}. with radius 1. CI- The circle is centered at the origin. with radius 2. -12_ In Desmos, you can also change the "graph paper" for polarfunct'ions This option is found in the settings menu {looks like a wrench in my browser}. Rather than a rectangular grid in the background of your graph, you get circles. Afull circle has 350\
