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. In addition, the TI-86 boasts 96 KB of user-available memory-three times more than the TI-85. 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. If that doesn't solve the problem, then you can consider replacing the calculator with a modern equivalent.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. If you have a Texas Instruments TI-84 Plus SE that is no longer working, you can first try replacing the 4xAAA + CR1620 3V batteries. The calculator was manufactured in Taiwan. It has 50 keys, and an LCD (liquid crystal) display. The Texas Instruments TI-84 Plus SE is a graphing calculator with 10 digits precision and formula input logic.
