**Graphing in
Mathcad**

**Objectives:**

Be able to create plots in Mathcad for:

1. data

2. function

__Graphing Data__

Here we have defined 7 (x,y) pairs. I have defined
x in terms of an index variable i and y as a vector, just so that you
can see that you can do it either way

Click on the

x-y plot button

and this is what

you get.

This is what you get when you

type y and x into their respective

place holders.

__Graphing Functions__

**The
Vander-Waals Equation**

**Redlich Kwong
Equation**

**Vanderwaals
and Redlich-Kwong in a single Plot**
