Conics: Graphing CirclesYou are watching: How to graph circles on ti 84 plusA. center at the origin: B. center at (h, k):

example A: Graph:

 Solution: Enter the equation right into Y= by addressing for y. get in the optimistic square root into Y1. Get in the an adverse square root into Y2, or go into the negation of Y1. If you choose ZOOM #6 (the typical window), the graph will show up to it is in an ellipse rather than a circle because of the 3/2 facet ratio that the viewing display screen (the conventional viewing screen is no a square).
