The keys along the right side of the keyboard are the common math functions. Page The Display Generally, the graphing calculator will continue to operate for one or two weeks after the low- battery message is first displayed. After this period, the TI Plus will turn off automatically and the unit will not operate. Batteries must be replaced. All memory should be retained.

Page 13 When an entry is executed on the home screen, the answer is displayed on the right side of the next line. Entry Answer The mode settings control the way the TI Plus interprets expressions and displays answers. Functions include absolute value, summation, numeric differentiation, numeric integration, and log base n.

Page Interchangeable Faceplates Busy Indicator When the TI Plus is calculating or graphing, a vertical moving line is displayed as a busy indicator in the top-right corner of the screen. When you pause a graph or a program, the busy indicator becomes a vertical moving dotted line. Display Cursors In most cases, the appearance of the cursor indicates what will happen when you press the next key or select the next menu item to be pasted as a character.

Carefully lift the faceplate away from the unit until it releases.

Using the Z-Score Equation

Be careful not to damage the faceplate or the keyboard. Page 17 Changing the Clock Settings 1. Using the Catalog to turn the clock on 1. If the clock is turned off, Press y N 2. Page 19 Entering an Expression To create an expression, you enter numbers, variables, and functions using the keyboard and menus.

Page 20 : The Catalog Help App contains syntax information for most of the functions in the catalog. Note Instructions An instruction initiates an action. For example, is an instruction that clears any drawn ClrDraw elements from a graph. Instructions cannot be used in expressions.

Using the invNorm Function

In general, the first letter of each instruction name is uppercase.

Page 23 scientific notation mode expresses numbers in two parts. The significant digits display with one digit to the left of the decimal. However, the number can have one, two, or three digits before the decimal; Page 24 sequence graphing mode plots sequences Chapter 6.

Connected, Dot plotting mode draws a line connecting each point calculated for the selected functions. Connected plotting mode plots only the calculated points of the selected functions. Sequential, Simul graphing-order mode evaluates and plots one function completely before the next Sequential function is evaluated and plotted.

To return to the mode screen, press z. Stat Diagnostics: Off, On displays a statistical regression calculation without the correlation coefficient r or the coefficient of determination r displays a statistical regression calculation with the correlation coefficient r , and the coefficient of determination r Page Recalling Variable Values 3.

If you entered an expression, it is evaluated. The value is stored to the variable. The variable contents are inserted where the cursor was located before you began these steps.

You can edit the characters pasted to the expression without affecting the value in Note: memory.

Scrolling Through Previous Entries on the Home Screen You can scroll up through previous entries and answers on the home screen, even if you have cleared the screen.

Page 31 When you press y [, all the expressions and instructions separated by colons are pasted to the current cursor location. Page Ti Plus Menus Continuing an Expression You can use as the first entry in the next expression without entering the value again or pressing y Z. On a blank line on the home screen, enter the function.

The TI Plus pastes the variable name to the screen, then the function. When you press a key that displays a menu, that menu temporarily replaces the screen where you are working. The cursor can be anywhere on the menu, and the item you select need not be displayed on the screen.

Functions in the first level, such as squaring, are evaluated before negation.

You can use lists to evaluate expressions at multiple values simultaneously and to graph a family of curves. For details, refer to:Chapter Statistics You can perform one- and two-variable, list-based statistical analyses, including logistic and sine regression analysis.

Page Error Conditions Archiving Archiving allows you to store data, programs, or other variables to user data archive where they cannot be edited or deleted inadvertently.

Archiving also allows you to free up RAM for variables that may require additional memory.

Critical Z Value TI 83: Easy Steps for the InvNorm Function

Read the chapter for details. You can download this App from education. If you use two lists in the same expression, they must be the same length. For example, L returns a negative number, because squaring is evaluated before negation. Displays the equation solver. The Solver equation is assumed to be equal to zero. To use the solver to solve an equation such as , enter in the Note Page 51 3. Enter an initial guess for the variable for which you are solving.

This is optional, but it may help find the solution more quickly. Also, for equations with multiple roots, the TI Plus will attempt to display the solution that is closest to your guess.

Page Math Num number Operations squares next to the previous solution and disappear. To control that process, enter bounds that are relatively close to the solution and enter an initial guess within those bounds.

If is omitted, round decimals decimals is rounded to the digits that are displayed, up to 10 digits.

Page 55 For a given , the result of is the same as the result of for nonnegative numbers Note: value int iPart and negative integers, but one integer less than the result of for negative noninteger iPart numbers.

Page 56 remainder returns the remainder resulting from the division of two positive whole numbers, remainder dividend , each of which can be a list. The divisor cannot be zero. If both arguments are lists, they divisor must have the same number of elements. If one argument is a list and the other a non-list, the non- list is paired with each element of the list, and a list is returned. Page Entering And Using Complex Numbers converts a fraction to a decimal or a decimal to a fraction.

Page 58 On the TI Plus, complex numbers can be stored to variables. Also, complex numbers are valid list elements. In Real mode, complex-number results return an error, unless you entered a complex number as input. For example, in Real mode returns an error; in mode returns an answer.

Internally, the TI Plus converts all entered trigonometric values to radians, but it does not convert values for exponential, logarithmic, or hyperbolic functions.
