# Graphics Of Transcendental Functions; Graph Of Ln(x) - HP 49g+ User Manual

Graphing calculator.

Move the cursor to the upper left corner of the display, by using the š
and — keys.
To display the figure currently in level 1 of the stack press L REPL .
Note: To save printing space, we will not include more graphs produced by
following the instructions in this Chapter. The user is invited to produce those
graphics on his or her own.

## Graphics of transcendental functions

In this section we use some of the graphics features of the calculator to show
the typical behavior of the natural log, exponential, trigonometric and
hyperbolic functions.
You will not see more graphs in this chapter, instead
the user should see them in the calculator.
