If you have Khoros set up correctly on your machine,
then typing in

should bring up the
following window (Figure 1). Since we
have not specified a function, **xprism2**

gives us an
enchanting view of a black square. On the left of the void
there is a button marked . Click
on the **xprism2****Plot** button, and you will find a whole new
window (Figure 2)
opening just for you, which includes the methods of inputting
a function.

```
test2.text
```

What should be in the text file? Since we are plotting a
two-dimensional function, you must write the function in
terms of one variable, namely **x**. For multiplication,
use the `*****' symbol, for exponentiation, use
`******', for division use `**/**', and for addition
and subtraction use `**+**' and `**-**'. You may also add the domain and the number of
tick marks in the file. For example, if you wish **x**
to range from **-¶** to **3.14** with **40** tick
marks for the function * f(x) = sin(x) · cos(x) + x² *,
then the text file would read as

```
f(x) = sin(x)*cos(x) + x**2
```

.

x=(-pi, 3.14,40)

Once this has been done (successfully), you should get a graph that resembles the following:

Figure 2, choose the

Figure 5 , you will see
the Once you click on the button ,the resulting graph should resemble Figure 6 below.
