When trying to graph or trace it brings up the error message:
ERR:invalid dim
How do I correct or clear this?
Press [STAT] to open the Statistics editor. From the menu that displays, select PlotsOFF and press [ENTER] twice. The calculator answers "Done".
Open the [Y=] editor to enter the functions to be drawn. Use the Trace ONLY after the graph has been displayed.
To clear any message without necessarily removing the conditions that yield the error press the CLEAR button.
