Ti-89 Titanium Graphing Calculator Update
The Ti-89 Titanium Graphing Calculator: A Farewell to a Classic
The iconic Ti-89 Titanium Graphing Calculator by Texas Instruments, as of the beginning of 2025, is officially being discontinued. For many students, educators, and professionals, this device has been a trusted calculator for two decades. Let's take a closer look at its history, features, and the alternatives available as we bid farewell to a calculator that has shaped the way math and science are taught.
A Brief History of the Ti-89 and Ti-89 Titanium
The original Ti-89 Graphing Calculator was released in 1998, making a significant impact in the world of advanced mathematics and engineering. Six years later, on January 7th, 2004, Texas Instruments announced the Ti-89 Titanium, alongside the Ti-84 Plus, Ti-84 Plus Silver Edition, and BA II Plus Professional Financial Calculator. The Ti-89 Titanium brought several enhancements over its predecessor, ensuring it remained a go-to device for students tackling calculus, differential equations, and engineering problems.
Key Differences Between the Ti-89 and Ti-89 Titanium:
-
Modern Design: The Ti-89 Titanium adopted a longer (taller) shape, aligning with the form factor introduced by the Ti-84 Plus and later seen in models like the Ti-84 Plus C Silver Edition. This was a departure from the Ti-89's design, which closely resembled the older Ti-83 (and the modern Ti-83 Plus Graphing Calculator).
-
Mini USB Port: A Mini USB port made it easier to connect the calculator to computers and other calculators for data transfer, a significant upgrade from the Ti-89.
-
Improved Display: The Ti-89 Titanium featured a better display, enhancing readability for complex calculations and graphs.
-
Software Applications: The Titanium supported a wider range of pre-installed and downloadable software applications (19 at the time of announcement in 2004), further extending its functionality.
The Timeline of Texas Instruments Calculators with CAS capabilities
As the Ti-89 Titanium rose to prominence, Texas Instruments began to introduce a series of graphing calculators that offered similar or advanced functionalities. These models catered to evolving classroom needs and technological advancements:
-
Ti-Nspire CAS: Released in the Summer of 2007, this model introduced a Computer Algebra System (CAS) that allowed for symbolic manipulation of equations, making it a powerful alternative for advanced math.
-
Ti-Nspire CX and Ti-Nspire CX CAS: Released in winter of 2011, these models brought color displays and more intuitive navigation, elevating the user experience and enhancing visual learning for graphing and calculations.
-
Ti-Nspire CX II and Ti-Nspire CX II CAS: Announced on March 7th, 2019, the Ti-Nspire CX II and Ti-Nspire CX II CAS graphing calculators featured faster processing, dynamic geometry capabilities, and Python programming support, making them versatile tools for modern classrooms.
These advancements marked the gradual evolution of TI graphing calculators with CAS capabilities, ensuring that students and educators had access to cutting-edge number crunchers that met the demands of modern curriculum.
Alternatives to the Ti-89 Titanium
While the Ti-89 Titanium has been a cornerstone for advanced math and science education, Texas Instruments has introduced several alternatives over the years. These models not only match but often surpass the functionality of the Ti-89 Titanium.
Top Replacement Models:
-

-
Key Features: Full symbolic algebra and calculus functionality, along with all the features of the Ti-Nspire CX II.
-
The Legacy of the Ti-89 Titanium
Since its release in 2004, the Ti-89 Titanium has undergone a few minor hardware updates and software enhancements, maintaining its relevance in classrooms and professional settings alike. However, as technology evolves, Texas Instruments is shifting its focus to newer models like the Ti-Nspire series, which better meet the needs of today’s learners and educators.
