<p>I will be taking the Math II in December but I am new to the graphing calculator.
I have learned how to draw graphs with the graphing calculator but each time I try it with my calculator, what it says is<br>
ERR INVALID DIM</p>
<p>Is it that my calculator is defective or I dont know how to use it. Could anyone tell me what to do to get the graphs.</p>
<p>Thanks</p>
<p>Is this a TI-83 or 84? If it is, you may have “Plot1,” “Plot2,” and/or “Plot3” at the top of the Y= screen highlighted. If this is the case (they’re bolded if selected, I believe), go all the way up to those and press enter to deselect them.</p>
<p>Try resetting the calculator:
2nd Function
+
7
1
2</p>
<p>(: press those buttons in order and it should reset everything-works every time</p>
<p>thanks so much guys. I have done as you said and it’s working now.</p>
<p>^no problem (: always willing to help people out on here</p>
