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.
There's also a new function evaluation table which shows numeric output for function, polar, parametric, and differential equation modes. You can also view multiple lists and attach formulas to those lists for automatic computations.
A new aspect of the TI-86 is the ability to customize product functionality with machine language programs downloaded from TI's Web site. 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. Cables shown are for informative purposes only and are not included in rental.
