This applet arises from a very nice article by Pavel Pech, entitled "The use of dynamic geometry systems and computer algebra systems in IBME" in [b]Implementing Inquiry in Mathematics Education[/b], Peter Baptist & Dagmar Raab (Eds), Fibonacci Project, 2012 (available at: [url]http://fibonacci.uni-bayreuth.de/resources/[/url], clicking on "Resources for implementing inquiry", companion resource #2).
