Recursion Use this mode to store recursion formulas, to generate a numeric table of different solutions as the values assigned to variables in a function change, and to draw graphs. Conic Graphs Use this mode to draw graphs of conic sections.
k About the Function Menu Use the function keys (1 to 6) to access the menus and commands in the menu bar along the bottom of the display screen. You can tell whether a menu bar item is a menu or a command by its appearance. k Status Bar The status bar is an area that displays messages and the current status of the calculator. It is always displayed at the top of the screen. • Icons are used to indicate the information described below. This icon: Indicates this: The current battery level.
k About Display Screens This calculator uses two types of display screens: a text screen and a graph screen. The text screen can show 21 columns and 8 lines of characters, with the bottom line used for the function key menu. The graph screen uses an area that measures 384 (W) × 216 (H) dots. Text Screen Graph Screen k Normal Display The calculator normally displays values up to 10 digits long. Values that exceed this limit are automatically converted to and displayed in exponential format.

Chapter 2 Manual Calculations 1. Basic Calculations k Arithmetic Calculations • Enter arithmetic calculations as they are written, from left to right. • Use the - key to input the minus sign before a negative value. • Calculations are performed internally with a 15-digit mantissa. The result is rounded to a 10digit mantissa before it is displayed. • For mixed arithmetic calculations, multiplication and division are given priority over addition and subtraction. Example Operation 56 × (–12) ÷ (–2.5) = 268.
Example 1 100 ÷ 6 = 16.66666666... Condition Operation Display 100/6w 16.66666667 4 decimal places !m(SET UP) ff 1(Fix)ewJw *1 16.6667 5 significant digits !m(SET UP) ff 2(Sci)fwJw *1E+01 1.6667 Cancels specification !m(SET UP) ff 3(Norm)Jw 16.66666667 *1 Displayed values are rounded off to the place you specify. Example 2 200 ÷ 7 × 14 = 400 Condition Operation 3 decimal places Display 200/7*14w 400 !m(SET UP) ff 1(Fix)dwJw 400.
k Calculation Priority Sequence This calculator employs true algebraic logic to calculate the parts of a formula in the following order: 1 Type A functions • Coordinate transformation Pol (x, y), Rec (r, θ) • Functions that include parentheses (such as derivatives, integrations, Σ, etc.
Example 2 + 3 × (log sin2π2 + 6.8) = 22.07101691 (angle unit = Rad) 1 2 3 4 5 6 • When functions with the same priority are used in series, execution is performed from right to left. exln 120 → ex{ln( 120)} Otherwise, execution is from left to right. • Compound functions are executed from right to left. • Anything contained within parentheses receives highest priority.
Since the calculation result uses a common denominator, calculation result still may be displayed using the ' format even when coefficients (a´, c´, d´) are outside the corresponding range of coefficients (a, c, d). Example: 3 + 11' 2 3 ' 2 10' ' + = 110 11 10 Calculation Examples This calculation: Produces this type of display: 2 × (3 – 2' 5) = 6 – 4' 5 ' format 35' 2 × 3 = 148.492424 (= 105 ' 2)*1 Decimal format 150' 2 = 8.485281374*1 25 23 × (5 – 2' 3) = 35.
Calculation Examples This calculation: Produces this type of display: 78π × 2 = 156π π format 123456π × 9 = 3490636.164 (= 11111104 π)*3 Decimal format 105 2 568 71 π = 105 π 824 103 π format 258 π = 6.533503684 3238 2 129 π *4 1619 Decimal format *3 Decimal format because calculation result integer part is |106| or greater. *4 Decimal format because number of denominator digits is four or greater for the a b π form.
If you execute a calculation in which a multiplication sign has been omitted immediately before a fraction (including mixed fractions), parentheses will be inserted automatically as shown in the examples below. 1 1 ): 2 3 3 Example (2 × Example (sin 2 × → 2 4 4 ): sin 2 5 5 ( 13 ) → sin 2 ( 45 ) k Overflow and Errors Exceeding a specified input or calculation range, or attempting an illegal input causes an error message to appear on the display.

Executing the test produces the following results. • Time differential (A) level of significance P = 0.2458019517 The level of significance (p = 0.2458019517) is greater than the significance level (0.05), so the hypothesis is not rejected. • Temperature differential (B) level of significance P = 0.
6. Confidence Interval A confidence interval is a range (interval) that includes a statistical value, usually the population mean. A confidence interval that is too broad makes it difficult to get an idea of where the population value (true value) is located. A narrow confidence interval, on the other hand, limits the population value and makes it difficult to obtain reliable results. The most commonly used confidence levels are 95% and 99%.
u General Confidence Interval Precaution Inputting a value in the range of 0 < C-Level < 1 for the C-Level setting sets a value you input. Inputting a value in the range of 1 < C-Level < 100 sets a value equivalent to your input divided by 100. k Z Interval u 1-Sample Z Interval 1-Sample Z Interval calculates the confidence interval for an unknown population mean when the population standard deviation is known. Perform the following key operations from the List Editor.
u 1-Prop Z Interval 1-Prop Z Interval uses the number of data to calculate the confidence interval for an unknown proportion of successes.

k Data (Constants, Text, Formula) Input Basics First let’s have a look at a few basic procedures that apply regardless of the type of data you are inputting. u To overwrite data currently in a cell with new data 1. Move the cell cursor to the cell where you want to input data. • If the cell you select already contains data, the following step will overwrite the existing data with new input. 2. Use the calculator’s keys to input data.
k Inputting a Constant (Value, Calculation Result, Number Sequence) into a Cell A constant is something whose value is fixed as soon as you finalize its input. A constant can be either a numeric value, or a calculation formula (such as 7+3, sin30, A1×2, etc.) that does not have an equal sign (=) in front of it. Inputting sdaw, for example will cause the value 0.5 (the calculation result) to appear in the cell (when Deg is selected as the Angle unit).
Item 1st Cell Description Input the reference name (A1, B2, etc.) of the cell where you want the first value of the number sequence to be input. Specify a cell here only if the starting cell is different from the one you specified in step 1 of this procedure. Example: al(B)bw (B1) • Each time you press w after inputting data for a setting item, the highlighting will move to the next setting item. You also can use f and c to move the highlighting upwards and downwards as required.
u Formula Input Example A 1 B PRICE C QUANTITY TOTAL 2 35 15 525 3 52 15 780 4 78 20 1560 Procedure 1. Input the text for line 1, and the applicable values in cells A2 through B4. 2.

Press 2(EDIT)2(COPY). • This will go into paste standby for the selected data, indicated by the 1 menu item changing to (PASTE).
When you are cut and paste a range cells, reference names that affect relationships within the range are changed accordingly when the range is pasted in order to maintain the correct relationship, regardless of whether they are relative or absolute reference names. → Cutting the B1:C1 range of cells that includes the formula =B1+5 and pasting it into B2:C2.
k Inputting the Same Formula into a Range of Cells Use the Fill command when you want to input the same formula into a specified range of cells. The rules governing relative and absolute cell name references are the same as those for copy and paste. When you need to input the same formula into cells B1, B2, and B3, for example, the Fill command lets you do so by inputting the formula once, into cell B1. Note the following about how the Fill command handles cell name references in this case.
k Sorting Constant Data Note that only constant data can be sorted. You can select multiple columns within a single line or multiple lines within a single column for sorting. u To sort constant data 1. Select a range of column cells in a single row or a range of row cells in a single column. • See “To select a range of cells” (page 9-7). • A Syntax ERROR message will appear if any of the cells in the range you select contain data other than constant data. 2.
u To insert a row or column of blank cells 1. Perform one of the following operations to specify the location of the insert and the number of rows or columns to be inserted. • To insert rows Starting with the row immediately below of the row where you want the insert to be performed, select the same number of rows that you want to insert. Example: To insert three rows above row 2, you could select A2:A4, B2:C4, etc.
3. Using Special Spreadsheet Mode Commands The Spreadsheet mode has a number of special commands like CellSum(, which returns the sum of a range of cells, and CellIf(, which specifies branching conditions. These special commands can be used inside of formulas. k Special Spreadsheet Mode Command List “Input Key Operation” operations can be performed during cell input only. You can omit anything enclosed in brackets ([ ]) in the Syntax of each command.
Command Description CellMedian( (Median of Cells) Returns the median value in a specified range of cells. Input Key Operation: 5(CELL)4(Med) Syntax: CellMedian(start cell:end cell[)] Example: =CellMedian(A3:C5) Returns the median value of the data in cell range A3:C5. CellSum( (Sum of Cells) Returns the sum of the data in a specified range of cells. Input Key Operation: 5(CELL)5(Sum) Syntax: CellSum(start cell:end cell[)] Example: =CellSum(A3:C5) Returns the sum of the data in cell range A3:C5.
4.

Decision depends on whether or not “ERROR” is displayed in the cell whose settings are being configured.
- 2(ERROR) ... Inputs “ERROR” into the conditional expression. For example, you can use this to input A1=ERROR. Decision depends on whether or not “ERROR” is displayed in the cell being referenced in the conditional expression (A1 in the example here). - 3(BLANK) ... Inputs “BLANK” into the conditional expression. Decision depends on whether or not the cell being referenced in the conditional expression is blank. - 4(And) ... Inputs the logical operator “And” into the conditional expression. - 5(Or) ...
u Procedure 1. Select the range of cells B3:C4. 2. Press 6(g)5(CONDIT) to display the Condition screen. • Condition1 appears first, so configure the first condition here. 3.

Chapter 15 Picture Plot Picture Plot is an application that lets you plot points (that represent coordinates) on a photograph, illustration, or other graphic and perform various types of analysis based on the plotted data (coordinate values). For example, the photograph below shows the nozzles of a fountain shooting thin streams of water at different angles.
• Add time values (T) to the coordinate values (X, Y) and plot points on the T-X plane or T-Y plane. This makes it possible to produce the mathematical expressions and graphs of the correlation between horizontal direction movement and time, and the correlation between vertical direction movement and time. Regression graph T-X regression graph (left side) During full-screen display of an X-Y coordinate graph, SKETCH and G-SOLVE operations can be used the same way they are in the Graph mode.
