TI-89 Titanium

This is the mother of all graphing calculators and a must for engineering majors. This is TI's most sophisticated calculator, with such features as 3D graphing, upgradable flash ROM, built-in assembly language programming, and a generous amount of user-available memory. It now includes a mini USB port. The TI-89 Titanium lets you perform the expected functions of an advanced model--basic math, algebra, calculus, graphs, matrices, and statistical functions--and do cool stuff like creating animations, graphing 3-D rotations, and plotting contours.

Graphing functions include basic function graphing, parametric graphing, polar graphing, sequence graphing, 3-D graphing, and differential-equation graphing. Additionally, the TI-89 Titanium includes symbolic manipulation, constants and measurement units, statistics and data plots, a numeric solver, a text editor, programming capabilities, tables, a split-screen function, variable management, and the ability to link to other calculators or a computer.


This calc handles calculus, engineering, trigonometric, and financial functions. With the TI-84, you can view an equation, its graph, and the coordinates all at one time. Jump from point to point by entering a number. Several useful plot types are available, including scatter, box-and-whisker, XY-line, histogram, and normal probability plots.

Advanced statistics and regression analysis, graphical analysis, and data analysis are readily accessed, along with features for calculus, engineering, financial, logarithm, trigonometry, and hyperbolic functions--all crucial tools for advanced analysis. With its clear display and fast processing, the calculator incorporates graphing tools for mathematics and science course work, including statistics and finance.


For students of college mathematics (Calculus), engineering, and science, this is a great calc. The TI-86 includes a function evaluation table, deep entry recall, seven different graph styles with multiple line and shading options, and slope and direction fields for differential equations.

Besides the strong graphing abilities, the TI-86 also has powerful calculus features like integration, derivatives, minimums, maximums, roots, and arcs. It also supports Z80 assembly language programming.

TI-83 Plus

This calc handles calculus, engineering, trigonometric, and financial functions. The 83 plus is more of a beginner calc for students in math or science classes.
