HP 48gII @ADD, L@@@OK@@@, L@@@OK@@@, f (x) = 1 exp(− x 2 ), Plotting an expression of the form y = f(x)

Plotting an expression of the form y = f(x)

As an example, let's plot the function,

f (x) = 1 exp(− x 2 )

2π 2

•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) = ƒ. 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-
