In order to help everyone learn how to use their graphing calculator I have set up this discussion forum for us to share what we know about our calculators. I have included several threads in an attempt to organize the postings. Feel free to ask questions about your calculator.
To earn 2 points (up to a maximum of 10 points for five individual postings) describe how to use one feature of your calculator. These postings must be substantive, just describing how to do something simple such as adding two numbers is not enough! The posting might be a response to someone else's question or an original idea.
