[. . . ] · Equations also include calculation ending instructions, such as "=". Functions 6 Priority Levels in Calculation This calculator performs operations according to the following priority: Functions preceded by their argument Fractions (1m4, etc. ) (x -1, x 2, n!, etc. ) y x, xr Implied multiplication of a memory value (2Y, etc. ) Functions followed by their argument (sin, cos, 1 etc. ) Implied multiplication of a function (2sin 30, A , etc. ) 4 nCr, nPr ×, ÷ +, - AND OR, XOR, XNOR =, M+, M-, M, DEG, RAD, GRAD, DATA, CD, r, xy, and other calculation ending instructions · If parentheses are used, parenthesized calculations have precedence over any other calculations. · Refer to the calculation examples for each function. · In the Line editor, the following symbols are used: : to indicate an expression's power. (m, @ ", · @ Y) · : to separate integers, numerators, and denominators. (W, @ k) · When using @ O or @ W in the Line editor, values are entered in the following way: · logn (base, value) · abs value OPERATION MANUAL PRINTED IN CHINA / IMPRIMÉ EN CHINE / IMPRESO EN CHINA 07BGK (TINSE1278EHZZ) INTRODUCTION Thank you for purchasing the SHARP Scientific Calculator Model EL-W531/W531G/W531H/W531HA/W535. [. . . ] · Do not throw batteries into a fire as they may explode. Sum of squares of samples (x data) Mean of samples (y data) Sample standard deviation (y data) Population standard deviation (y data) Sum of samples (y data) Replacement Procedure 1. EL-W531/W531G/W535: Remove the used battery by prying it out with a ball-point pen or other similar pointed device. Press the RESET switch (on the back) with the tip of a ball-point pen or similar object. If the display does not appear as shown, remove the battery, reinstall it, and check the display once again. sy y y y 2 Using Math Drill and × Table 1. Math Drill: Use u and d to select the number of questions (25, 50, or 100). × Table: Use u and d to select a row in the multiplication table (1 to 12). Math Drill: Use l and r to select the operator type for questions (+, -, ×, ÷, or +-×÷). × Table: Use l and r to select the order type ("Serial" or "Random"). When using Math Drill or × Table (random order only), questions are randomly selected and will not repeat except by chance. Press j or N to clear the entered number and then enter the correct answer. · If the answer is correct, " " appears and the next question is displayed. Correction after pressing _: Use u and d to display the previously entered data set. To reverse the display order to descending (latest first), press the u key. Press @ u or @ d to jump the cursor to the beginning or end of the data set. Each data set is displayed with "X:", "Y:", or "F:". Fig. 3 Calculation Ranges 19 See step 6 above. · Within the ranges specified, this calculator is accurate to ±1 of the 10th digit of the mantissa. However, a calculation error increases in continuous calculations due to accumulation of each calculation error. (This is the same for y x, xr, n!, e x, ln, etc. , where continuous calculations are performed internally. ) Additionally, a calculation error will accumulate and become larger in the vicinity of inflection points and singular points of functions. · Calculation ranges ±10-99 to ±9. 999999999 × 1099 and 0. If the absolute value of an entry or a final or intermediate result of a calculation is less than 10-99, the value is considered to be 0 in calculations and in the display. Display of results using r Calculation results may be displayed using r when all of the following conditions are met: · When intermediate and final calculation results are displayed in the following form: P P ±a eb ± c d f · When each coefficient falls into the following ranges: 1 a < 100; 1 < b < 1, 000; 0 c < 100; 1 d < 1, 000; 1 e < 100; 1 f < 100 · When the number of terms in the intermediate and final calculation results is one or two. Note: The result of two fractional terms that include r will be reduced to a common denominator. Automatic Power Off Function This calculator will turn itself off to save battery power if no key is pressed for approximately 10 minutes.
