Lesson 21: Plotting a Function
A function takes one or more arguments as inputs and transforms
them inathematically into exactly one output. A function can be
plotted by graphing a series of outputs against a corresponding series
of inputs.
Plotting functions on the HP 48 is a matter of doing the following:
Ent.ering or choosing the function to plot.
Declaring the independent variable and the horizontal range of
that you want to view.
Either declaring the vertical range to be displayed or choosing to
let the HP 48 automatically scale it for you.
Making sure that the angle mode (Degrees, Radians, Grads) is
properly set.
Setting the other plot display options.
All of these steps can be accomplished smoothly and quickly in the
PLOT application.
Example: Plot f(x) = sin.r.
Step 1: Open the PLOT application. You may or may not already
have a function entered in EQ:.
