Plotting an expression of the form y = f(x)
In this section we present an example of a plot of a function of the form
y = f(x).
In order to proceed with the plot, first, purge the variable x, if it is defined in the
current directory (x will be the independent variable in the calculator's PLOT
feature, therefore, you don't want to have it pre-defined). Create a sub-
directory called 'TPLOT' (for test plot), or other meaningful name, to perform the
following exercise.
As an example, let's plot the function,
Θ
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
