Essential for AP Calculus, college math, and beyond, the TI-89 is the most logical handheld technology for advanced mathematics studies. Enhanced with Flash technology, this handheld gives you the flexibility to add calculator software applications and additional functionality, providing long-term value.

Built-in advanced mathematics software includes a Computer Algebra System (CAS) enabling you to manipulate mathematical expressions and functions (factor, solve, differentiate, integrate, and more). It also includes differential equations, 2-D graphing and data analysis, 3-D graphing with rotations, linear algebra, interactive numeric solver, constants, unit conversions, statistical regressions, and optional assembly language programming.

All this power is generated by only 4 AAA batteries with a lithium battery backup to protect RAM memory during main battery change. The calculator comes in an impact-resistant slide case.
