TI-83: Activities | Guidebook | Keyboard | Programs Easy to use graphing tool with enhanced TI-82 features, plus advanced statistics and finance. Some of its features are interactive graphing includes displaying the expression being traced and number entry for prompts in CALC operations during tracing, graph-table split screen allows to trace the graph and scroll the table simultaneously, equations solver solves for variable in an equation interactively (great for doing "what ifs"), display results of hypothesis tests graphically and numerically, compatible with CBL and CBR. TI-85: Activities | Guidebook | Keyboard | Programs This model features interactive calculus commands that allow for analysis of graphs while viewing it, operation of functions on values, variables, or lists (one element at a time), operation of functions on both complex and real arguments, definition and display of vectors in rectangular, cylindrical or spherical coordinates, the powerful tool SOLVER for working with equations and solving for any variable, allows and saves matrices up to 30 ×30. TI-89: Activities | Guidebook | Keyboard | Programs This model is also a CAS and its software can be electronically upgraded. Some of its
features are symbolic manipulation of equations, graphing of 3D and contour plots, exact
symbolic solutions of some first and second order differential equations, split screens
and "petty print" (display of math notation as we write it). |
