User manual SHARP EL-520XBWH

[. . . ] Single-variable statistics mode (STAT x): @m1 Used to perform 1-variable statistical calculations. Two-variable statistic mode (STAT xy): @m2 Used to perform 2-variable statistical calculations. When executing mode selection, temporary memories, statistical data and last answer memory will be cleared even when reselecting the same mode. Conversion between decimal and sexagesimal numbers can be performed. [. . . ] · Exhausted batteries left in the calculator may leak and damage the calculator. · Batteries must be replaced only with others of the same type. · Do not throw batteries into a fire as they may explode. X Rectangular coord. Polar coord. · The calculation result is automatically stored in memories X and Y. Value of r or x: X memory Value of or y: Y memory Replacement Procedure 1. [EL-509V/EL-531V] Remove the used batteries by prying them with a ball-point pen or other similar pointed device. [EL-509VH/EL-520XBWH] First insert the " ­ " side to the spring. If the display does not appear as shown, remove the batteries reinstall them and check the display once again. Modify Function (11) Selecting the Display Notation and Decimal Places The calculator has four display notation systems for displaying calculation results. When FIX, SCI, or ENG symbol is displayed, the number of decimal places can be set to any value between 0 and 9. Displayed values will be reduced to the corresponding number of digits. 100000÷3= [Floating point] ª100000/3= [Fixed decimal point] @f [TAB set to 2] @i 2 [SCIentific notation] @f [ENGineering notation] @f [Floating point] @f 33333. 33333 33333. 33333 33333. 33 3. 33×104 33. 33×103 33333. 33333 Hard Case In this calculator, all calculation results are internally obtained in scientific notation with up to 12 digits for the mantissa. · When performing calculations using constants, constants will be displayed as K. Entered data are kept in memory until @ c or @ m 1 (2) are pressed. [Data Entry] Single-variable data Data k Data & frequency k (To enter multiples of the same data) Two-variable data Data x & Data y k Data x & Data y & frequency k (To enter multiples of the same data x and y. ) [Data Correction] Correction prior to pressing k: Delete incorrect data with ª. Correction after pressing k: Press > to confirm the latest entry and press @ J to delete it. Functions (4) BEFORE USING THE CALCULATOR Key Notation Used in this Manual In this manual, key operations are described as follows: ex ln x To specify ex : To specify ln : To specify x : @e I @KX · Refer to the operation examples of each function. · The results of inverse trigonometric functions are displayed within the following range: = sin­1 x, = tan­1 x DEG RAD GRAD ­90 90 ­---- 2 2 ­100 100 = cos­1 x 0 180 0 0 200 Functions that are printed in orange above the key require @ to be pressed first before the key. Numbers are not shown as keys, but as ordinary numbers. Random Numbers A pseudo-random number with three significant digits can be generated by pressing @ ` =. Each random number is generated on the basis of the value stored in memory Y (pseudo-random number series). Statistical Calculation Formulas (14) Power On and Off Press ª to turn the calculator on, and @F to turn it off. Clearing Methods There are three clearing methods as follows: Clearing operation ª @c RESET : Clear × : Retain * Independent memory M. 2 * Temporary memories A-D, X and Y, statistical data, and last answer memory. 1 Refer also to the operation examples sheet. In the statistical calculation formulas, an error will occur when: · the absolute value of the intermediate result or calculation result is equal to or greater than 1 × 10100. · an attempt is made to take the square root of a negative number. Entry (Display) M*1 × × A-D, X, Y*2 STAT, ANS × Angular Unit Conversions (5) ERROR AND CALCULATION RANGES Errors An error will occur if an operation exceeds the calculation ranges, or if a mathematically illegal operation is attempted. [. . . ] When an error occurs, pressing < (or >) automatically moves the cursor back to the place in the equation where the error occurred. Edit the equation or press ª to clear the equation. Each time @ g are pressed, the angular unit changes in sequence. Memory Calculations (6) This calculator has 6 temporary memories (A-D, X and Y), one independent memory (M) and one last answer memory. Independent memory and temporary memories are only available in the normal mode. [. . . ]
