• First, enter the PLOT SETUP environment by pressing, „ô. Make
sure that the option Function is selected as the TYPE , and that ‘X’ is
selected as the independent variable ( INDEP ). Press L@@@OK@@@ to
return to normal calculator display. The PLOT SET UP window should
look similar to this:
• Enter the PLOT environment by pressing „ñ(press them
simultaneously if in RPN mode). Press @ADD to get you into the
equation writer. You will be prompted to fill the right-hand side of an
equation Y1(x) = . Type the function to be plotted so that the
Equation Writer shows the following:
• Press ` to return to the PLOT SETUP window. The expression
‘Y1(X) = EXP(-X^2/2)/ √ (2* π )’ will be highlighted. Press L@@@OK@@@ to
return to normal calculator display.
• Enter the PLOT WINDOW environment by entering „ò (press
them simultaneously if in RPN mode). Use a range of –4 to 4 for H-
