User manual SHARP EL-512H

[. . . ] : Indicates that a numerical value is stored in the independent memory. M INTRODUCTION Thank you for purchasing the SHARP Scientific Calculator Model EL-509WM/ 509WS. About the calculation examples (including some formulas and tables), refer to the reverse side of this English manual. Refer to the number on the right of each title on the manual for use. After reading this manual, store it in a convenient location for future reference. BEFORE USING THE CALCULATOR Key Notation Used in this Manual In this manual, key operations are described as follows: To specify ex : @e To specify ln : I To specify F : Kü Functions that are printed in orange above the key require @ to be pressed first before the key. [. . . ] Press ªOM to clear the independent memory (M). [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. · Random function . . . . . . . . . . . . . . . . . . . . . . Y memory · r, xy . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . X memory (r or x), Y memory ( or y) · Temporary memories and last answer memory are cleared even when the same mode is reselected. · Use of R or K will recall the value stored in memory using up to 14 digits. Chain Calculations · This calculator allows the previous calculation result to be used in the following calculation. · The previous calculation result will not be recalled after entering multiple instructions. · In the case of utilizing postfix functions (¿ , sin, etc. ), you can perform a chain calculation even when the previous calculation result is cleared by the use of the ª or @c keys. Fraction Calculations This calculator performs arithmetic operations and memory calculations using fractions, and conversion between a decimal number and a fraction. When a decimal number having a fractional part is converted into a binary, pental, octal, or hexadecimal number, the fractional part will be truncated. 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). 0 (SD) 1 (LINE) 2 (QUAD) 3 (EXP) 4 (LOG) 5 (PWR) 6 (INV) : Single-variable statistics : Linear regression calculation : Quadratic regression calculation : Exponential regression calculation : Logarithmic regression calculation : Power regression calculation : Inverse regression calculation Statistical Calculation Formulas Type Linear Exponential Logarithmic Power Inverse Quadratic Regression formula y = a + bx y = a · ebx y = a + b · ln x y = a · xb 1 y=a+b-- x y = a + bx + cx2 The following statistics can be obtained for each statistical calculation (refer to the table below): 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. · No solution exists in the quadratic regression calculation. Normal Probability Calculations · P(t), Q(t), and R(t) will always take positive values, even when t<0, because these functions follow the same principle used when solving for an area. Values for P(t), Q(t), and R(t) are given to six decimal places. When to Replace the Batteries If the display has poor contrast, the batteries require replacement. Cautions · Fluid from a leaking battery accidentally entering an eye could result in serious injury. 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.
