# GeoGebra Tutorial 19 – Basic Spreadsheet Recording

This is the 19th tutorial of the GeoGebra Intermediate Tutorial Series. If this is your first time to use GeoGebra, you might want to read first the GeoGebra Essentials Series.

A spreadsheet is a program that can be used to organize data in tables and  perform mathematical computations. Recently, GeoGebra integrated spreadsheet in its graphical user interface. In this tutorial, we learn how to use the GeoGebra spreadsheet.

The figure above shows the different parts of a spreadsheet.  The following are the descriptions. You should familiarize yourself with these terms because we are going to use them in this tutorial and the two more tutorials to come.

1. Column – the horizontal division of the spreadsheet. Columns are labeled with letters.
2. Row – the vertical division of a spreadsheet. Rows are labeled with numbers.
3. Column/Row Headers – The part of the spreadsheet where the column/row labels are placed.
4. Cells – the smallest unit in a spreadsheet, or the intersection of a column and a row.
5. Cell Addresses – the name used to refer to a particular cell; that is, their column header and row header. For example, cell A1 is the cell on the first column and the first row. F3 is the cell with the orange box in Figure 1.
6. Cell Pointer – a rectangular box that indicates the cell is being edited.

In this tutorial, we use the Record to Spreadsheet tool to record the coordinates of a moving point along a graph of a function.  We graph the function f(x) = x2,  and construct point P with coordinates (a,f(a)), where a is a value on a slider. We  then record the coordinates of the traces of P on the spreadsheet window. The output of this tutorial is shown in Figure 2.
