User manual SHARP EL-509WM/WS

[. . . ] ENGLISH HYP SCIENTIFIC CALCULATOR : Indicates that h has been pressed and the hyperbolic functions are enabled. If @H are pressed, the symbols "2ndF HYP" appear, indicating that inverse hyperbolic functions are enabled. EL-509WM MODEL EL-509WS OPERATION MANUAL PRINTED IN CHINA 04KGK (TINSE0780EH01) ALPHA: Indicates that K (STAT VAR), O or R has been pressed, and entry (recall) of memory contents and recall of statistics can be performed. FIX/SCI/ENG: Indicates the notation used to display a value and changes by SET UP menu. DEG/RAD/GRAD: Indicates angular units and changes each time G is pressed. STAT : Appears when statistics mode is selected. [. . . ] When a decimal number having a fractional part is converted into a binary, pental, octal, or hexadecimal number, the fractional part will be truncated. Likewise, when the result of a binary, pental, octal, or hexadecimal calculation includes a fractional part, the fractional part will be truncated. In the binary, pental, octal, and hexadecimal systems, negative numbers are displayed as a complement. W · Use K and R to perform a STAT variable calculation. Time, Decimal and Sexagesimal Calculations Conversion between decimal and sexagesimal numbers can be performed. In addition, the four basic arithmetic operations and memory calculations can be carried out using the sexagesimal system. Notation for sexagesimal is as follows: Data Entry and Correction Entered data are kept in memory until @c are pressed or mode selection. Before entering new data, clear the memory contents. [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. ) · Up to 100 data items can be entered. With the single-variable data, a data item without frequency assignment is counted as one data item, while an item assigned with frequency is stored as a set of two data items. With the two-variable data, a set of data items without frequency assignment is counted as two data items, while a set of items assigned with frequency is stored as a set of three data items. [Data Correction] Correction prior to pressing k immediately after a data entry: Delete incorrect data with ª, then enter the correct data. Correction after pressing k: Use [] to display the data previously entered. Press ] to display data items in ascending (oldest first) order. To reverse the display order to descending (latest first), press the [ key. Each item is displayed with `Xn=', `Yn=', or `Nn=' (n is the sequential number of the data set). Display the data item to modify, input the correct value, then press k. Using &, you can correct the values of the data set all at once. or appears, more data items can be browsed by pressing · When [ or ]. · To delete a data set, display an item of the data set to delete, then press @J. · To add a new data set, press ª and input the values, then press k. degree minute second Coordinate Conversions · Before performing a calculation, select the angular unit. Y y 0 x X P (x, y) Y P (r, ) r 0 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 Modify Function In this calculator, all calculation results are internally obtained in scientific notation with up to 14 digits for the mantissa. However, since calculation results are displayed in the form designated by the display notation and the number of decimal places indicated, the internal calculation result may differ from that shown in the display.
