<p>So I have a TI-89 but I really have no idea how to use it at all. I used it in Stats this year but I have no idea how to graph or how to use the y= editor or any of that stuff.</p>
<p>Can someone point me in the direction of a tutorial or something? Whenever I try to graph something a window pops up and it says "Dimension"....What does this mean and how can I fix this.</p>
<p>I feel so stupid =[</p>
