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. About the calculation examples (including some formulas and tables), refer to the reverse side of this English manual. [. . . ] Correction after pressing k: Use [] to display the data previously entered. Press ] to display data items in ascending (oldest first) order. To reverse the display order to descending (latest first), press the [ key. Each item is displayed with `Xn=', `Yn=', or `Nn=' (n is the sequential number of the data set). Display the data item to modify, input the correct value, then press k. Using &, you can correct the values of the data set all at once. · To delete a data set, display an item of the data set to delete, then press @J. · To add a new data set, press ª and input the values, then press k. Complex number entry Q Rectangular coordinates x-coordinate + y-coordinate Ü or x-coordinate + Ü y-coordinate W Polar coordinates rÖ r: absolute value : argument · On selecting another mode, the imaginary part of any complex number stored in the independent memory (M) will be cleared. · A complex number expressed in rectangular coordinates with the y-value equal to zero, or expressed in polar coordinates with the angle equal to zero, is treated as a real number. · Press 0 to return the complex conjugate of the specified complex number. SIMULATION CALCULATION (ALGB) If you have to find a value consecutively using the same formula, such as plotting a curve line for 2x2 + 1, or finding the variable for 2x + 2y =14, once you enter the equation, all you have to do is to specify the value for the variable in the formula. Usable variables: A-F, M, X and Y Unusable functions: Random function · Simulation calculations can only be executed in the normal mode. · 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. 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. 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. Creates lists with elements from the left column of each matrix. (matAL1, matBL2, matCL3, matDL4) Mode changes from matrix mode to list mode.
