INITIAL SET UP Mode Selection m0: Normal mode (NORMAL) m1: Statistic mode (STAT) m2: Equation mode (EQN) m3: Complex number mode (CPLX) m4: Matrix mode (MAT) m5: List mode (LIST) INTRODUCTION Thank you for purchasing the SHARP Scientific Calculator Model EL-506W/546W. [. . . ] · 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) fill(value, row, column) cumul matrix name aug(matrix name, matrix name) identity value Returns a matrix with dimensions changed as specified. Returns the identity matrix with specified value of rows and columns. Performing Calculations Q Press m0. 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. · 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. · 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 STATISTICAL CALCULATIONS Press m1 to select the statistics mode. 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. det matrix name trans matrix name matlist (5) matAlist (6) Returns the determinant of a square matrix. Returns the matrix with the columns transposed to rows and the rows transposed to columns. (matAL1, matBL2, matCL3, matDL4) Mode changes from matrix mode to list mode. (matAL1, L2, L3, L4) Mode changes from matrix mode to list mode. 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. Single-variable statistical calculation Statistics of Q and value of the normal probability function SIMULTANEOUS LINEAR EQUATIONS Simultaneous linear equation with two unknowns (2-VLE) or with three unknowns (3-VLE) may be solved using this function. Q 2-VLE: m20 W 3-VLE: m21 LIST CALCULATIONS This function enables the saving of up to 4 lists of 16 elements for calculations. Enter [/] will display the list edit buffer along with Linear regression calculation 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´) · · · · · the value of each item (`SIZE', and then each element, e. g.
