new model of handheld calculators from TI

Dear colleagues,

Texas Instruments has launched a new model of handheld  calculators  – TI-Nspire CAS. This new instrument has the functionality of the graphing calculator TI-Nspire with a Computer Algebra System (CAS) built in. Here is the picture of this new calculator:

Price: $150.00 approximately

This new product is much more powerful  than very well known TI-89.  If you would like to know more, please go to the web page:  http://www.ti-nspire.com/tools/nspire/features/nspire_cas.html.

The TI-Nspire line of handhelds has greatly improved hardware compared to older TI graphing calculators. The new LCD screen has a higher resolution (320×240 pixels) and is capable of displaying sixteen shades of gray.

The TI-Nspire line features the ability to display dynamically linked variables from application to application. For example, a calculator application with an equation stored in the variable x might be displayed alongside a graphing application which would graph the shared variable. Changes made to variables made in one application will affect the others in real time.

In order to deal with this split-screen interface, the Nspire has the larger screen and a cursor-like control. By using the cursor many things can be adjusted fluently. Application window sizes can be adjusted. Equations can be dragged and manipulated while the coefficients of the equations change accordingly in real time. The graphing window scale and center can also be controlled using the cursor

The TI-Nspire CAS calculator stores and displays values symbolically instead of as floating-point numbers, and includes algebraic functions like deSolve(…) and eigVc(…) as well as calculus based functions, including limits, derivatives, and integrals. For this reason, the TI-Nspire CAS is more comparable to the TI-89 Titanium and Voyage 200.

No doubts, this new instrument can be used with a great success in our classrooms at UPR-RUM to teach Pre-calculus, Calculus, Differential Equations, Numerical Analysis, Statistics, Linear Algebra, Discrete Mathematics, Geometry,  Physics, and other disciplines.

Please consider this tool as a great help in teaching mathematics. The application of this new technology in our classrooms can bring a lot of valuable benefits. First of all, our students will get a powerful impulse to be motivated in mastering mathematical disciplines.
