How to enter a new program. Hit PRGM. Open the EDIT menu. Type in the name of the program. Choose a descriptive name up to 8 letters. Keep in mind that the program names will eventually appear alphabetized and only 5 of the 8 letters will appear in the menu. Hit ENTER. Now you are ready to type in each line of your program. TI already uses for a built-in variable (such as LOG). • Whatever you store in a particular memory location stays there until it is replaced by some-thing else either by you or by executing a program containing that name. NOTE: The TI allows you to enter upper and lower case letters, and it distinguishes between them.

Introduction The instructions for entering, tti, exiting, and editing are the same for any program. The actual program on this sheet allows you to quickly evaluate a function. This may be helpful when determining a reasonable window for graphing or investigating the value of a limit.

Usually this contains instructions for finding a particular command. Anything in RED denotes a button on the calculator. Anything in BLUE denotes a tl on the calculator that requires hitting another button first. Some menus have many entries. You might proogram to use the What about savarkar movie songs button. Your calculator manual will be very valuable for finding the commands and buttons needed for programming.

Choose progrzm descriptive name up to 8 letters. Keep in mind that the program names will eventually appear alphabetized and only 5 of the 8 letters will appear in the menu. Now you are ready to type in each line of your program.

Any words in the program that begin with an uppercase letter Disp, for example are actually commands and should be retrieved from a menu or key. If you need to delete a prlgram use DEL. It deletes to the right of the cursor. If you need to insert characters use INS. It inserts to the left of the cursor. The Program This program has four lines.

When you are finished, hit QUIT.

Chapter Programming Calling a Program from Another Program On the TI, any stored program can be called from another program as a subroutine. In the program editor, enter the subroutine program name on a command line by itself. When the program name is encountered as the calling program runs, the next command executed is the first command.

Page Resetting All Memory And Defaults Before doing an activity, press : to clear the screen except keystroke combinations, this guidebook places brackets before the entry retrieval and integer-part examples.

In the example, press Z to enter a Using a Variable in an Expression Editing an Expression You need not move the cursor to the end of the line to evaluate the expression. Display the open brace On the TI, list. Enter the list elements. Separate each element from the next with a comma. Select the close brace menu to specify the end of the list. The MATH menu shifts up. Enter a value for which you want to find the square root.

Evaluate the expression. The square root of is displayed. If the measurement is negative, use parentheses. To plot a graph, you must store an unevaluated expression to a built-in equation variable. Changing the Graph Style of a Function In the equation editor, the icon to the left of each equation specifies the style in which the graph of that equation appears when you plot it on the graph screen.

Then each selected graph is plotted in the order in which it is listed in the equation editor. Trace the function. As you trace, the displayed value is the solution for 5 cos x at the current value, which also Page Deselecting A Function Plot the graph on the graph screen. Since you deselected , the TI only plots To select a function in the equation editor, repeat these steps.

SELCT both selects and deselects functions. Move the zoom-box cursor to a point that is to be a corner of the redefined graph screen, and then mark the point with a small square. You must install them before you can turn on the calculator. A lithium backup battery is installed in the calculator already. To express - and All settings and memory contents are retained by the Constant Memory APD turns off the TI automatically after about four minutes of non-use to extend battery life.

Page Entering Numbers T the subtract key. Page Using Scientific Or Engineering Notation When you include scientific- or engineering-notation numbers in an expression, the TI 10 exponent is a multiple of 3. The mode settings page 34 and the size of the number determine the notation of displayed answers. To set alpha-lock when the entry cursor is displayed, press - n 1.

To cancel alpha-lock, press 1 1. Also, if you press a key that has no blue character above it, such as 6, 3, or! Page Cursor Direction Keys Deletes a character at the cursor; to continue deleting to the right, hold down 3 Clears the current entry on the home screen; : : clears the entire home screen Chapter 1: Operating the TI " moves cursor right - " moves cursor to end of entry Page Entering Expressions And Instructions Entering an Expression An expression is any combination of numbers and variables that serve as arguments for one or more functions.

On the TI, you typically enter an expression in the same order as you would write it on paper. For example, , and are expressions. Some their required and optional instructions take more than one argument, as indicated by an open parenthesis arguments.

Page Entering Consecutive Entries page The Busy Indicator When the TI is calculating or graphing, a moving vertical line is displayed as the busy indicator in the top-right corner of the screen. When you pause a graph or a program, the busy indicator is replaced by the pause indicator, a moving vertical dotted line.

Page Diagnosing An Error To restart graphing, select an instruction that displays the graph. Diagnosing an Error If a syntax error occurs within When the TI detects an error, it returns an error a stored equation during message, such as program execution, select Page Retrieving Multiple Entries Retrieving the Last Answer When an expression is evaluated successfully on the home screen or in a program, the TI stores the answer to a built-in variable called complex number, list, vector, matrix, or string.

When you turn off the TI, the value in is retained in memory. Menu-Displaying Method Press a key that has a menu name on it Page Exiting Removing A Menu The of the screen. Constant Memory feature retains current mode settings when the TI is turned off. All numbers, including elements of matrices and lists, are displayed according to the mode settings.

Deleting a Variable from Memory You cannot delete a TI From the home screen or in a program, to delete from memory one user-created variable built-in variable. You can use these vowels in variable names and text. Page Keyboard Mathematical Functions If you use two lists, vectors, or matrices in the same expression, they must be equal in dimension.

The most common mathematical functions are on the TI keyboard. For syntax, details, and examples of these functions, refer to the A to Z Reference. For details about fPart specific syntax options and examples, refer to the A to Z value Reference. It is Degree treated as radians in Radian angle mode. For details about seq specific syntax options, refer to the A to Z Reference. The calculus functions return values with respect to any user-created variable, to built-in variables evalF , and evalF nDer der1 nDer , variable can be a real For example: flow Chapter The common constants built into the TI You cannot edit the value of a built-in constant.

You can create your own constants and add them to the user-created constant menu for easy access. You can enter a value later. If you select when the PREV For example, you can convert inches to yards, quarts to liters, or expression is valid. Otherwise, the TI order of evaluation will perform the L The TI converts it to Page Converting A Value Expressed As A Rate You also can return this result using only a forward slash, as in: Number Bases The number base mode setting Chapter 1 controls how the TI interprets an entered number and displays results on the home screen.

For value detailed syntax descriptions, refer to the A to Z Reference. Page Results Of Boolean Operations Results of Boolean Operations Both the argument and the When a Boolean expression is evaluated, the arguments are converted to hexadecimal result must be within defined integers and the corresponding bits of the arguments are compared, as this table shows. Page Defining A Graph Defining a Graph This chapter describes the process for graphing functions in process is similar for each TI graphing mode.

Chapters 8, 9, and 10 describe the unique aspects of polar, parametric, and differential equation graphing modes. Chapter 6 describes various graphing tools, many of which you can use in all graphing modes. Page The Graph Menu Each graphing mode has a unique equation editor. You must select the graphing mode and number base mode before you enter the functions.

The TI retains in memory all equations stored to the unique graph format settings and window variables.

If the function is deselected, its equals sign is not highlighted. Only selected functions are plotted when the TI plots a graph. If functions are stored in the equation editor, move the cursor down until a blank function is To move to the beginning or displayed.

Page Notes About Defining Function Equations Chapter 5: Function Graphing Notes about Defining Function Equations You can edit expressions you inserted using You can include functions, variables, constants, matrices, matrix elements, vectors, vector elements, lists, list elements, complex values, or other equations in the equation. If you include matrices, vectors, or complex values, the equation must evaluate to a real number at each point.
