In calculus the other day we collected some data with a CBR2 (motion detector) and a racquet ball rolling up an incline. This was a great activity to discuss the relationship between a position vs. time graph and velocity-time. I'm going to work on writing up a procedure for this to be student led activity rather than just a demonstration. I love the dynamic nature of Data & Statistics application on the TI-Nspire.
Tonight I'm going camping with the family. Check out the calculus that came up the last time I went camping.
Update 12/18/2008: Today on timath.com/calculus an activity I wrote was posted. It gives more documentation about using the CBR2 motion detector with the TI-Nspire CAS. "Gettin' the Swing" is the name of the activity. It is in the archive & it is #11689 on the Activity Exchange.
