TI-84 Plus Interactive Manual

Every chapter of the TI-84 Plus Silver Edition guidebook, rewritten as an interactive manual. Search any function, browse the index, or follow one of 619 guided tutorials: the keys to press light up in the manual and on the calculator itself. Open it next to the calculator ▶

• Chapter 1
  Operating the TI-84 Plus Silver Edition

  Everything you need to start using the calculator: the keyboard and the 2nd and ALPHA keys, the home screen, entering and editing expressions, MODE settings, menus, variables, STO and RCL, ENTRY and Ans, order of operations, and what to do when an error appears.

• Chapter 2
  Math, Angle, and Test Operations

  Keyboard math, the MATH menu (fractions, roots, calculus, Solver), NUM, CPX and PRB tabs, complex numbers, the ANGLE menu, and the TEST relational and Boolean operators.

• Chapter 3
  Function Graphing

  Define, graph and explore functions Y=f(X): the Y= editor, graph styles, window and format settings, the free-moving cursor, TRACE, every ZOOM and ZOOM MEMORY item, and the CALC menu (value, zero, minimum, maximum, intersect, dy/dx and the integral).

• Chapter 4
  Parametric Graphing

  Graph curves in which X and Y are both defined by a third variable T: Par mode, the X1T/Y1T… editor, Tmin/Tmax/Tstep, and exploring parametric graphs with TRACE, ZOOM and the CALC menu.

• Chapter 5
  Polar Graphing

  Graph polar equations r=f(θ): Pol mode, the polar Y= editor (r1 to r6), the θmin, θmax and θstep window variables, graph formats, TRACE, ZOOM and CALC in polar graphs.

• Chapter 6
  Sequence Graphing

  Graph sequences u(n), v(n) and w(n) in Seq mode: nonrecursive and recursive definitions, the sequence window variables, Time, Web and phase-plot axes, TRACE, and a comparison with the TI-82.

• Chapter 7
  Tables

  Evaluate your Y= functions at a list of X values: set up the table with TblStart, ΔTbl and the Auto/Ask options, define and edit dependent variables, then scroll the table and change its step.

• Chapter 8
  Draw Instructions

  Draw on top of a graph: lines, tangents, functions, inverses, shaded regions, circles, text, free-hand pen strokes, points and pixels, and save graphs as pictures (Pic) or graph databases (GDB). Covers the DRAW, DRAW POINTS and DRAW STO menus.

• Chapter 9
  Split Screen

  Show a graph and a second screen at the same time. Covers the Horiz (top/bottom) and G-T (graph/table, left/right) split-screen modes, moving between the two halves, which screens stay full-size, and the pixel limits for Pxl-On(, Text( and Output( in each mode.

• Chapter 10
  Matrices

  Define, edit, display and calculate with matrices [A] to [J]: the MATRX menus and matrix editor, the MTRX shortcut, matrix arithmetic, and the MATRX MATH functions such as det(, rref(, augment( and the row operations.

• Chapter 11
  Lists

  Create, name, store, edit and display lists; attach formulas to them; and use the LIST NAMES, LIST OPS and LIST MATH menus (SortA(, dim(, seq(, cumSum(, augment(, mean(, sum(, stdDev( and more).

• Chapter 12
  Statistics

  Enter and edit data in the stat list editor, calculate one- and two-variable statistics, fit regression models, draw stat plots (scatter, xyLine, histogram, box plots, normal probability) and use the statistical variables, from the home screen or a program.

• Chapter 13
  Inferential Statistics and Distributions

  Hypothesis tests and confidence intervals (Z, T, proportion, chi-square, F, regression and ANOVA), their input editors and output variables, plus the DISTR probability functions and distribution shading.

• Chapter 14
  Applications

  The APPS menu and the built-in Finance application: the TVM Solver, time-value-of-money functions, cash flows (npv, irr), amortization (bal, ΣPrn, ΣInt), interest conversion, dbd( and the payment method, plus notes on the other preloaded apps.

• Chapter 15
  CATALOG, Strings, Hyperbolic Functions

  Browse the alphabetical CATALOG of every function and instruction, enter strings and store them in Str0–Str9, use the six string functions (Equ►String(, expr(, inString(, length(, String►Equ(, sub() and the six hyperbolic functions.

• Chapter 16
  Programming

  Write, edit, run and manage TI-BASIC programs: the program editor, the PRGM CTL control instructions (If, For(, While, Goto, Menu(…), the PRGM I/O input and output instructions, subroutines, and what the emulator does with assembly and link-port instructions.

• Chapter 17
  Activities

  Complete worked projects that tie the calculator together: the quadratic formula, a box-volume optimization, box plots, piecewise functions and inequalities, nonlinear systems, the Sierpinski triangle, cobweb plots, a guessing game program, the unit circle, areas between curves, a Ferris wheel, the Fundamental Theorem of Calculus, polygon areas and mortgage payments.

• Chapter 18
  Memory and Variable Management

  Check free memory, delete variables, clear the last-entry storage and all lists, archive and unarchive variables, group variables, run garbage collection and reset RAM, defaults, archive or all memory from the MEMORY menu.

• Chapter 19
  Communication Link

  Sending and receiving programs, lists and other variables between calculators or a computer with a link cable. In the emulator, files take the place of the cable.

• Appendix A
  Functions and Instructions

  An A–Z reference of every function and instruction: syntax, what it does, and the keys or menu that paste it — in the same order as the CATALOG.

• Appendix B
  Reference Information

  Reference tables for variables, statistics and financial formulas, order of operations and other things to know, every ERR: message with its cause and cure, and numeric accuracy and function limits.

• Appendix C
  Service and Warranty Information

  Batteries, product support, service and warranty details for the physical calculator.
