User manual SHARP EL-5020

[. . . ] This product, including accessories, may change due to upgrading without prior notice. SHARP strongly recommends that separate permanent written records be kept of all important data. Data may be lost or altered in virtually any electronic memory product under certain circumstances. Therefore, SHARP assumes no responsibility for data lost or otherwise rendered unusable whether as a result of improper use, repairs, defects, battery replacement, use after the specified battery life has expired, or any other cause. [. . . ] , where positive and negative integral values exist depending on the interval. Following these tips will allow results of calculations with greater accuracy and will also shorten the calculation time. [Random Numbers] A pseudo-random number, with three significant digits from 0 up to 0. [Random Dice] To simulate a die-rolling, a random integer between 1 and 6 can be generated by pressing @`1®. [Random Coin] To simulate a coin flip , 0 (head) or 1 (tail) can be randomly generated by pressing @`2®. [Random Integer] An integer between 0 and 99 can be generated randomly by pressing @`3®. [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. ) Storing a new equation in each memory will automatically replace the existing equation. note: · Calculation results from the functions indicated below are automatically stored in memories X or Y replacing existing values. X memory (r or x), Y memory ( or y) · Use of R or K will recall the value stored in memory using up to 14 digits. Upon completing the calculation, press @ to perform calculations using the same formula. Performing simulation calculation will cause memory locations to be overwritten with new values. After selecting the statistics mode, select the desired sub-mode by pressing the number key corresponding to your choice. to change statistical sub-mode , reselect statistics mode (press m1) , then select the required sub-mode. 0 (SD) : Single-variable statistics 1 (LINE) : Linear regression calculation 2 (QUAD) : Quadratic regression calculation 3 (EXP) : Exponential regression calculation 4 (LOG) : Logarithmic regression calculation 5 (PWR) : Power regression calculation 6 (INV) : Inverse regression calculation The following statistics can be obtained for each statistical calculation (refer to the table on the next page): Statistics of Q and W and, in addition, estimate of y for a given x (estimate y´) and estimate of x for a given y (estimate x´) In addition, estimate of y for a given x and estimate of x for a given y. (Since the calculator converts each formula into a linear regression formula before actual calculation takes place, it obtains all statistics, except coefficients a and b, from converted data rather than entered data. When performing calculations using a, b and c, only one numeric value can be held. The results obtained by this function may include a margin of error. To carry out addition, subtraction, multiplication, and division using complex numbers, press m3 to select the complex number mode. Results of complex number calculations are expressed in two modes: Q @}: Rectangular coordinate mode (xy appears. On selecting another mode, the imaginary part of any complex number stored in the independent memory (M) will be cleared. [. . . ] When results of calculations are in the list format, the list edit buffer with those results will be displayed. ) To save the result in L1-4, press ª, then press °2 and specify L1-4. Since there is only one list edit buffer, the previous data will be overwritten by the new calculation. In addition to the 4 arithmetic functions, x3, x2, and x­1, the following commands are available: Returns a list with size changed as specified. [. . . ]
