RE: Can someone walk me through graphing an equation on Plus42
Here is a quick step-by-step example to plot the algebraic function SIN(X) using the equation list.

1. Press the Shift MODES key.

2. Press the [RAD] softkey.

3. Press EQN key.

4. Press the [NEW] softkey.

5. Use the SIN key, the letter X and the closing ) key to enter the following equation: SIN(X)

6. Press the ENTER key to enter the new equation into the equation list. This will now be the current equation as indicated by the cursor.

7. Press the Shift PLOT key. This will bring up the Plot menu with the equation from the list as the current plotting equation.
   
8. Press the [PARM] softkey.
   
9. Press the [XAXIS] softkey.
   
10. Press the [X] softkey.
   
11. Press the EXIT key.

12. Press the [VIEW] softkey (not the VIEW key).

13. Enter the following plot range using the keypad and softkeys:
-4 [XMIN]
4 [XMAX]
-1 [YMIN]
1 [YMAX]

14. Press the [PLOT] softkey to see the plot for this function.
   

I used the following Plus42 site for reference.

Let me know if you have any problems.

Edit: The following PDF file has a more detailed version of the above example with more screenshots.
