Excellent resource to get you up to speed QUICKLY and efficiently with the TI89.
on October 17, 2011
This is a great tool to quickly learn the ins and outs of the TI89. I have the Titanium but this will work even for the plain old TI89. Yes, you can read the manual and use TI's online resources but who has time for that? If you are going to be using this for Calculus including differential equations etc this is the fastest way to get the most out of your device. Excellent tool. Another home run by MathTutorDVD.
Some of the lettering on the video showing the calculator screens seems hazy. This is NOT because the video or its production is bad but because the screen resolution on the TI89 is abysmal. In fact there are many complaints, especially by older folks like myself, who find reading the TI89 menus a royal pain. But because the calculator does so much so well and because TI has a lock on the calculator market the TI89 is used extensively in educational circles.
