E-1 Contents Important Information ..............................................................2 Sample Operations ...................................................................2 Initializing the Calculator .....................................
E-2 Impor tant Information • The displays and illustrations (such as key markings) shown in this User’s Guide are for illustrative purposes only, and may differ somewhat from the actual items they represent. • The contents of this manual are subject to change without notice.
E-3 • Never try to take the calculator apart. • Use a soft, dry cloth to clean the exterior of the calculator . • Whenever discarding the calculator or batteries, be sure to do so in accordance with the laws and regulations in your particular area.
E-4 Reading the Display The display of the calculator shows expressions you input, calculation results, and various indicators. Input expression Indicators Calculation result • If a ' indicator appears on the right side of the calculation result, it means the displayed calculation result continues to the right.
E-5 Using Menus Some of the calculator’s operations are performed using menus. Pressing N or w , for example, will display a menu of applicable functions.
E-6 6 Fix 7 Sci 8 Norm Specifies the number of digits for display of a calculation result. Fix: The value you specify (from 0 to 9) controls the number of decimal places for displayed calculation results. Calculation results are rounded off to the specified digit before being displayed.
E-7 Inputting Expr essions and V alues Basic Input Rules Calculations can be input in the same form as they are written. When you press = the priority sequence of the input calculation will be evaluated automatically and the result will appear on the display.
E-8 5th Negative sign (–) Note: When squaring a negative value (such as –2), the value being squared must be enclosed in parentheses ( ( - 2 ) w = ). Since x 2 has a higher priority than the negative sign, inputting - 2 w = would result in the squaring of 2 and then appending a negative sign to the result.
E-9 ! As shown above, the value or expression to the right of the cursor after 1Y (INS) are pressed becomes the argument of the function that is specified next.
E-10 3 To input 1.428571428571... (1.428571) B 1 . a ! ( k ) 428571 To calculate 1.021 + 2.312 B 1 . a ! ( k ) 021 e + 2 . a ! ( k ) 312 = Calculation result displayed as recurring decimal value: f Note: • You can specify up to 14 decimal places for the recurring decimal period.
E-11 Return to initial display format (fraction): f 1 ÷ 7 = 7 1 = 0.142857 = 0.1428571429 (Norm 1) B 1 / 7 ! = Display as fraction: f Display as recurring decimal: f Return to initial display format (Norm 1): f 7 1 = 0.
E-12 Display as recurring decimal: f Return to initial display format (Norm 1): f Conditions for Displaying a Calculation Result as a Recurring Decimal If a calculation result satisfies the following conditions, pressing f will display it as a recurring decimal value.
E-13 T oggling Calculation Results While Natural Display is selected, each press of f will toggle the currently displayed calculation result between its fraction form and decimal form, its ' form and decimal form, or its π form and decimal form.
E-14 1 = 1 2 2 4 − 3 B 4 - 1 ' ( ( ) 3 e 1 c 2 = 1 2 b 4 - 3 ' 1 ' 2 = 1 { 2 Note: • Mixing fractions and decimal values in a calculation while Linear Display is selected will cause the result to be displayed as a decimal value. • Fractions in calculation results are displayed after being reduced to their lowest terms.
E-15 3 + 3 : 3 × 3 3 + 3 S W (:) 3 * 3 = 6 = 9 Using Engineering Notation A simple key operation transforms a displayed value to engineering notation. Transform the value 1234 to engineering notation, shifting the decimal point to the right. 1234 = 1234 W 1.
E-16 results in Ans memory. PreAns memory can be used only in the COMP Mode. PreAns memory contents are cleared whenever the calculator enters another mode from the COMP Mode.
E-17 To multiply the contents of variable A by 10 (Continuing) S y (A) * 10 = 80 To recall the contents of variable A (Continuing) t y (A) 8 To clear the contents of variable A 0 1t (STO) y (A) 0 Independent Memory (M) You can add calculation results to or subtract results from independent memory.
E-18 Note: • You will not be able to execute prime factorization while a decimal value, fraction, or negative value calculation result is displayed. Trying to do so will cause a math error (Math ERROR). • You will not be able to execute prime factorization while the result of a calculation that uses Pol, Rec, ÷R is displayed.
E-19 sin, cos, tan, sin −1 , cos −1 , tan −1 : Trigonometric functions. Specify the angle unit before performing calculations. See 1 . sinh, cosh, tanh, sinh −1 , cosh −1 , tanh −1 : Hyperbolic functions. Input a function from the menu that appears when you press w .
E-20 Rnd(10÷3) = 3.333 (with Fix 3), both the displayed value and the calculator’s internal value become 3.333. Because of this a series of calculations will produce different results depending on whether Rnd is used (Rnd(10÷3) × 3 = 9.999) or not used (10 ÷ 3 × 3 = 10.
E-21 To convert rectangular coordinates ( ' 2 , ' 2 ) to polar coordinates v B 1 + (Pol) ! 2 e 1 ) (,) ! 2 e ) = r=2, =45 b 1 + (Pol) ! 2 ) 1 ) (,) ! 2 )) = r= 2 = 45 To convert pola.
E-22 Statistical Calculations (ST A T) To start a statistical calculation, perform the key operation N 2 (STAT) to enter the STAT Mode and then use the screen that appears to select the type of calculation you want to perform.
E-23 Important: • All data currently input in the Stat Editor is deleted whenever you exit the STAT Mode, switch between the single-variable and a paired- variable statistical calculation type, or change the Stat Format setting on the setup menu. • The following operations are not supported by the Stat Editor: m , 1m (M–), 1t (STO).
E-24 1N (SETUP) c 3 (STAT) 1 (ON) N 2 (STAT) 1 (1-VAR) 1 = 2 = 3 = 4 = 5 = ce 1 = 2 = 3 = 2 = A1 1 (STAT) 4 (Var) 2 ( o ) = A1 1 (STAT) 4 (Var) 3 ( σ x ) = Results: Mean: 3 Population Standard Deviation: 1.
E-25 Cr eating a Number T able from T wo Functions (T ABLE) TABLE generates a number table based on one or two functions. You can use the function f ( x ) or the two functions f ( x ) and g ( x ). See “Configuring the Calculator Setup” for more information.
E-26 Note: • The maximum number of rows in the generated number table depends on the setup menu table setting. Up to 30 rows are supported for the “f(x)” setting, while 20 rows are supported for the “f(x),g(x)” setting. • You can use the number table screen for viewing values only.
E-27 x 2 | x | 1 × 10 50 x –1 | x | 1 × 10 100 ; x G 0 3 ' x | x | 1 × 10 100 x ! 0 x 69 ( x is an integer) n P r 0 n 1 × 10 10 , 0 r n ( n , r are integ.
E-28 Displaying the Location of an Error While an error message is displayed, press d or e to return to the calculation screen. The cursor will be positioned at the location where the error occurred, ready for input. Make the necessary corrections to the calculation and execute it again.
E-29 Argument ERROR Cause: A non-integer argument was input for the random number function (RanInt#). Action: Input only integers for the argument. Befor e Assuming Malfunction of the Calculator ... Perform the following steps whenever an error occurs during a calculation or when calculation results are not what you expected.
