TI's Top Student Calculator

TI's Top Student Calculator Texas Instruments has added the TI-89 to its line of graphing calculators. Designed with engineers in mind, the calculator's advanced mathematics software features a Computer Algebra System (CAS) that allows you to evaluate expressions numerically or symbolically. In addition to 2-D graphing and analysis, the calculator features real-time rotation of 3-D surfaces and contour graphs. 

Students can solve linear and nonlinear systems of equations, and single or systems of differential equations. The software performs unit conversions and allows you to use units in equations and symbolic computations, as well as create and store your own custom units. The split-screen mode allows you to view two applications simultaneously.

The TI-89, featuring Flash technology, is one of the first electronically upgradable calculators. With TI Graph Link, educators can transfer downloadable upgrades and future applications from the TI Web site to update and customize the calculator to fit their curriculums. The calculator has 500K of memory to store programs, functions, and data. Other features include a high-resolution display, programming options to customize menus, dialog boxes and pop-up windows, and a printed catalog that provides syntax listings for every command and function.

The TI-89 costs $159.95. Educators can borrow one on a short-term basis through TI's Workshop Loan Program, and may also qualify for TI's volume purchase program. For more information, call (800) TI-CARES; e-mail: ti-cares@ti.com ; or see www.ti.com

Physics by Pictures

Teach students Physics by Pictures with Physics Academic Software's comprehensive presentation of physics fundamentals. Using dynamic simulations of various natural phenomenon, the program covers most major areas of physics, including thermodynamics and molecular physics.

The software allows students to manipulate physical conditions and examine the consequences, as well as develop their own scenarios. Built into the program are lists of mathematical and physical formulas, calculators for basic and scientific functions, tables of physical constants, circuit and optic simulators, and a chart of SI units. Another facet of the program takes a historical look at the experiments and scientific laws Newton, Kepler, and others. The package includes a user's manual and several program texts containing questions, problem-solving exercises, experiments, and other reference material.

Physics by Pictures requires a PC running Windows with a minimum 386 processor, 3 MB of free hard disk space, and a VGA graphics card. A single copy costs $275, a 10-copy lab pack is $1,100, and a high school site license is $690.
