TutorFox's review of the TI-89 Titanium Calculator
The TI-89 is a line of graphing calculator that is developed by Texas Instruments, otherwise known as TI. The TI-89 Titanium was released in the summer of '04 and serves as an upgrade to the regular TI-89 calculator. Though the TI-89 Titanium cannot be used on the ACT exam, it is permitted for the SAT Reasoning Test, SAT subject tests, AP Calculus, AP Physics, AP Chemistry, and AP Statistics.
The TI-89 Titanium runs on a Motorola 68000 CPU that has speeds of up to 16Mhz. The graphing calculator has 2.75MB of Flash Rom. It is basically TI's most advanced and fasted calculator currently on the market. The TI-89 features an IO port and is one of the few graphing calculators to feature a mini USB port. The mini USB is used to connect two TI-89 Titanium calculators. It is also connectable to a computer, allowing the graphing calculator to easily upgrade its operating system.
The TI-89's main advantage over other graphing calculator competitors is its unique Computer Algebra System. The TI-89's CAS can successfully evaluate and solve expressions in terms of algebraic variables. For instance, the TI-89 can solve equations in terms of x, y, z, etc..
This feature is extremely helpful in advanced courses in Calculus, Chemistry, and Physics.
In calculus, the TI-89 can take derivatives and integrations in terms of symbolic variables. The TI-89 Titanium adds implicit differentiation to the TI-89's arsenal.
In Chemistry, students can use the TI-89 to solve multivariable equations gases and other forms of matter.
For physics, the TI-89 can successfully take derivatives and integrations of complex expressions representing acceleration, velocity, and overall distance.
Ultimately, the TI-89 Titanium is by far the most powerful calculator in world due to its wide variety of functions, and its overall ease of use. TutorFox.com highly recommends purchasing a TI-89 Titanium.
