[. . . ] ENGLISH SCIENTIFIC CALCULATOR MODEL EL-506W EL-546W OPERATION MANUAL PRINTED IN CHINA / IMPRIMÉ EN CHINE / IMPRESO EN CHINA 04CGK (TINSE0719EHZZ) INTRODUCTION Thank you for purchasing the SHARP Scientific Calculator Model EL-506W/546W. 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 in the manual for use. After reading this manual, store it in a convenient location for future reference. [. . . ] · Before performing calculations, press ª to close the matrix edit buffer. · When results of calculations are in the matrix format, the matrix edit buffer with those results will be displayed. (At this time, you cannot return to the equation. ) To save the result in matA-D, press ª, then press °2 and specify matA-D. · Since there is only one matrix edit buffer, the previous data will be overwritten by the new calculation. · In addition to the 4 arithmetic functions (excluding divisions between matrices), x3, x2, and x­1, the following commands are available: dim(matrix name, row, column) cumul matrix name aug(matrix name, matrix name) identity value Returns a matrix with dimensions changed as specified. Appends the second matrix to the first matrix as new columns. The first and second matrices must have the same number of rows. Returns the identity matrix with specified value of rows and columns. Performing Calculations Q Press m0. W Input a formula with at least one variable. Input the value of the flashing variable, then press ® to confirm. The calculation result will be displayed after entering the value for all used variables. · Only numerical values are allowed as variables. · Upon completing the calculation, press @ to perform calculations using the same formula. · Variables and numerical values stored in the memories will be displayed in the variable input screen. To change a numerical value, input the new value and press ®. · Performing simulation calculation will cause memory locations to be overwritten with new values. 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 fill(value, row, column) Fills each element with a specified value. STATISTICAL CALCULATIONS Press m1 to select the statistics mode. The seven statistical calculations listed below can be performed. 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 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. rnd_mat(row, column) Returns a random matrix with specified values of rows and columns.
