HP50g small tips and trick

[Carsen]

I have a new tip/trick for the 50g.

To plot an equation from Level 1 of the stack, use the PLOT command. This will open the Plot Setup menu, where you can immediately press the ERASE and DRAW to produce the graph. And the PLOT command is easy to access. Just press SYMB GRAPH PLOT.

Then you can even add more functions to the graph with PLOTADD. And it sits right next to PLOT. Tinker around with these functions. This function blew my mind! I can now create equations on the stack and quickly plot them.

Of course, some situations may need more settings changed before drawing the graph (such as Zoom parameters, selecting the type of graph, etc.).

Example: Graph -1/2*X^2+6. Press the following keys when in RPN mode on the home screen.

2 INV CHS [ ' ] X ENTER [ White Shift ] SQ * 6 + SYMB GRAPH PLOT (choose the FUNCTION graphing type if it is not selected) ERASE DRAW (then edit the zoom as needed.)
