V. DRAW Menu

F. CIRCL

There are several ways to graph a circle on the TI-86. You can graph a circle in rectangular mode, parametric mode, and polar mode. However, these all require that a function or functions be entered. If you want to just draw a circle, you can do it through the DRAW menu, but it will just be a drawing of a circle and TRACE, TABLE, etc. do not apply. Access CIRCL by pressing .

Example: Draw a circle of radius 2 with center at (-2,-1). Use ZDECM so that the cursor moves in increments of 0.1.
