With the TI-86, you can link to other TI-86s and TI-85s via the input/output port, and to CBLs, CBRs, and computers.

The 64 x 128 high-contrast pixel screen displays eight lines of 21 characters each plus two levels of display menus. It also supports Z80 assembly language programming. Besides the strong graphing abilities, the TI-86 also has powerful calculus features like integration, derivatives, minimums, maximums, roots, and arcs. A new aspect of the TI-86 is the ability to customize product functionality with machine language programs downloaded from TI's Web site. You can also view multiple lists and attach formulas to those lists for automatic computations. The TI-86 runs with programs designed for the TI-85 and includes all the same matrix features, but with a new matrix editor that allows the user to view and edit matrices in two dimensions.
There's also a new function evaluation table which shows numeric output for function, polar, parametric, and differential equation modes. Work out the predicted y value by plugging in the corresponding x value into the regression line equation. Start off by finding the residuals, which is the distance from regression line to each data point.
In addition, the TI-86 boasts 96 KB of user-available memory-three times more than the TI-85. To calculate R2 you need to find the sum of the residuals squared and the total sum of squares. 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. Designed with power users in mind, the TI-86 graphing calculator has all the power and functionality of the popular TI-85 but with significant enhancements aimed at students of college mathematics, engineering, and science.
