cclancy asked the following question in the Physics forum:
Does anyone know how to graph x > 7 with Geometer's Sketchpad? Is it possible?
I consulted the chief Ontario Sketchpad guru, Shawn Godin and then replied:
It is possible to graph inequalities on a number line or in the plane.
Shawn Godin supplied the first sketch and I am not sure where I picked up the other.
I have been collecting resources for Sketchpad, including the mathforum discussion group where questions like this are routinely and professionally answered. If you need any help deconstructing the methods used in either sketch above, you can contact me through my blog.
Hope this helps,
Ross
Update (May 16): The inequalities in the plane sketch was sent to me by ! Paul Kunkel in response to a question on the Math forum. ! Scott Steketee is offering a similar sketch with custom tools to generate the inequations from the mathforum discussion group.
