User manual SHARP EL-520W

[. . . ] ENGLISH FIX/SCI/ENG: Indicates the notation used to display a value. DEG/RAD/GRAD: Indicates angular units. STAT Priority Levels in Calculation Operations are performed according to the following priority: Q Fractions (1l4, etc. ) W , engineering prefixes E Functions preceded by their argument (x-1, x2, n!, etc. ) R Yx, x¿ T Implied multiplication of a memory value (2Y, etc. ) Y Functions followed by their argument (sin, cos, etc. ) U Implied multiplication of a function (2sin30, etc. ) I nCr, nPr O ×, ÷ P +, ­ { AND } OR, XOR, XNOR q =, 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. SCIENTIFIC CALCULATOR MODEL : Appears when statistics mode is selected. : Indicates that a value is stored in the independent memory. : Indicates that the calculator is waiting for a numerical value to be entered, such as during simulation calculation. [. . . ] · The value obtained by this function may include a margin of error. If it is larger than acceptable, recalculate the solution after changing `Start' and dx values. · Change the `Start' value (e. g. to a smaller value) if: · no solution can be found (Error 2). · more than two solutions appear to be possible (e. g. · to improve the arithmetic precision. · The calculation result is automatically stored in the X memory. [Performing Solver function] Q Press m0. R Input `Start' value and press ®. Y Press ®. W COMPLEX NUMBER CALCULATIONS 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. ) W @{: Polar coordinate mode (r appears. ) · Use K and R to perform a STAT variable calculation. Data Entry and Correction Entered data are kept in memory until @c or mode selection. Before entering new data, clear the memory contents. [Data Entry] Single-variable data Data k Data & frequency k (To enter multiples of the same data) Two-variable data Data x & Data y k Data x & Data y & frequency k (To enter multiples of the same data x and y. ) · Up to 100 data items can be entered. With the single-variable data, a data item without frequency assignment is counted as one data item, while an item assigned with frequency is stored as a set of two data items. With the two-variable data, a set of data items without frequency assignment is counted as two data items, while a set of items assigned with frequency is stored as a set of three data items. [Data Correction] Correction prior to pressing k immediately after a data entry: Delete incorrect data with ª, then enter the correct data. 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. 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.
