<p>On a ti-84, is there any way to graph circles and ellipses and things. if so, how?</p>
<p>Also, can you factor with it and how?</p>
<p>you have to find programs for both of those functions i think</p>
<p>any ideas where?</p>
<p>You have to seperate the equation into a y= equation. PM me and I can help if you need more information. But I know that CAsio calculators graph circles, elipses, parabolas, and many others because there is a built in program. </p>
<p>If you need more info about how to seperate the equation into y= just PM me the equations you need and I can change it for you.</p>
<p>**However, on the TI-84 and other TI calculators the circle will appear as two lines.</p>
<p>try ticalc.org and go to the archives</p>
