User manual SHARP EL-546VA

[. . . ] If @H are pressed, the symbols "2ndF HYP" appear, indicating that inverse hyperbolic functions are enabled. 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 INTRODUCTION Thank you for purchasing the SHARP Scientific Calculator Model EL-546VA. About the calculation examples (including some formulas and tables), refer to the reverse side of this English manual. [. . . ] · If a floating point number does not fit in the specified range, the calculator will display the result using the scientific notation (exponential notation) system. See `Setting the Floating Point Numbers System in Scientific Notation' for details. · Press ", followed by 0, to display the following submenu: FIX SCI ENG NORM1 NORM2 ] Angular Unit Conversions Each time @g are pressed, the angular unit changes in sequence. Memory Calculations This calculator has 8 temporary memories (A-F, X and Y), one independent memory (M) and one last answer memory (ANS). The independent memory and temporary memories are only available in the normal mode. [Temporary memories (A-F, X and Y)] Press O and a corresponding variable key to store a value in memory. Press R and a corresponding variable key to recall a value from the memory. To place a variable in an equation, press K, followed by a desired variable key. [Independent memory (M)] In addition to all the features of temporary memories, a value can be added to or subtracted from an existing memory value. [Last answer memory (ANS)] The calculation result obtained by pressing = or any other calculation ending instruction is automatically stored in the last answer memory. Note: · Calculation results from the functions indicated below are automatically stored in memories X or Y. For this reason, when using these functions, be careful with the use of memories X and Y. · 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, 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. By using the modify function, the internal value is converted to match that of the display, so that the displayed value can be used without change in subsequent operations. STATISTICAL CALCULATIONS Statistical calculations are performed in the statistics mode. This calculator performs the seven statistical calculations indicated below. After selecting the statistics mode, select the desired sub-mode by pressing the number key corresponding to your choice. When changing to the statistical sub-mode, press the corresponding number key after performing the operation to select the statistics mode (press m1). Statistical Calculation Formulas Type Linear Exponential Logarithmic Power Inverse Quadratic Regression formula = a + bx = a · ebx = a + b · ln x = a · xb 1 y=a+b-- x y = a + bx + cx2 y y y y · Do not fit partially used batteries, and be sure not to mix batteries of different types. · Exhausted batteries left in the calculator may leak and damage the calculator. · Do not throw batteries into a fire as they may explode. Replacement Procedure 1. [EL-509W/531W/531WG] Remove the used batteries by prying them out with a ball-point pen or other similar pointed device. If the display does not appear as shown, remove the batteries reinstall them and check the display once again. 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. [. . . ] Should this occur, wash with clean water and immediately consult a doctor. · Should fluid from a leaking battery come in contact with your skin or clothes, immediately wash with clean water. · If the product is not to be used for some time, to avoid damage to the unit from leaking batteries, remove them and store in a safe place. · Do not leave exhausted batteries inside the product.
