The spreadsheet is utility tool that can be adapted to many different explorations, presentations, and simulations in mathematics. There are spreadsheets available on almost any platform. An essential feature should be the ability to make graphs and charts from the matrix of data. First we will construct a graph of the function y = f(x). Let us start with f(x) = 2x, with x ranging from 0 to 20 as shown below. To see the spreadsheet, click here.

Suppose the graph was y = x^2 the following graph below will be obtained. Click here for the spreadsheet.

What of if the equation was f(x) = 5sin(x) with x varying from 0 to 21 .It can be noted that excel can be a graphing tool. To access the file that created this image, click here.
