The third column of this data table calculates
v2 - the square of the value in the first data
column.

Formulas allow you to specify a calculation that the Graphical
AnalysisTM software will apply automatically to all of
your data. This can be very handy and a real time saver. It is
easy to do, too. Here's the deal:
- First, add a new column
to your data table.
- In Graphical AnalysisTM, ll formulas start
with an "=" sign.
- Enter your formula using standard "computer algebra" notation
- "*" for multiplication, etc.
- If your formula refers to another data column (and it
probably will), be sure that you type the name exactly
as shown in the column heading, including case.
- You can select
mathematical functions to be inserted into your formula
from the "Column Formula" submenu in the Data Menu.
After entering the formula in the first line of the column header,
you can enter its units (if any) in the second line.
