k Rectangular Coordinate Graph
Inputting the Graph command in the Run-Matrix mode enables drawing of rectangular
coordinate graphs.
coordinate graphs.
1. From the Main Menu, enter the Run-Matrix mode.
2. On the Setup screen, change “Input/Output” setting to “Linear”.
3. Configure V-Window settings.
4. Input the commands for drawing the rectangular coordinate graph.
5. Input the function.
