*Know about a freeware graph tool*

- Roadkil's Graph is a freeware application that draws graphs from algebraic formulas entered by users.
- Functions such as sine, cosine, tan, log, log natural and powers can be used.
- The x and y range displayed on the axis can be altered to zoom in and zoom out on the graph.
- Grid lines and value labels are displayed on the graph for easy reading.
- Graphs can also be printed on any standard printer.

Go to http://www.softpedia.com/progDownload/Roadkils-Graph-Download-44235.html

to download it.

This is the main screen of the tool.

You just have to write the function and click on draw, graph will be obtained. I am using this tool ,just to visualise the shape of the graphs of various functions.
