Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator
Every time i go to graph a parabola, i press"y=" and i type in my formula. but when i hit graph a message pops up that says "ERR: INVALID DIM". i dont know what to do. i think it might have something to do with the "Plot1", "Plot2", and "Plot3", being highlited. PLEASE HELP ME!!!!!!
Make sure all plots are off. to do this, 2nd-Y=. Highlight selection 4 (PlotsOff), and press enter twice. It should say Done.
Next, press the ZOOM button, and select number 6 (ZStandard). This will restore your window settings to default.
If those fail, press 2nd-+ to bring up the Memory menu. Press 7 (Reset), and select Default. This will not delete anything, it will just restore your settings.
