User manual SHARP EL-506

[. . . ] ENGLISH SCIENTIFIC CALCULATOR MODEL Determination of the Angular Unit This calculator has three angular units: DEG (°), RAD (Radians) and GRAD (g). Press @G to specify the angular unit. Time, Decimal and Sexagesimal Calculations (11) EL-506V EL-546V OPERATION MANUAL PRINTED IN CHINA / IMPRIMÉ EN CHINE 00LUP (TINSK0443EHZZ) Conversion between decimal and sexagesimal numbers can be performed. In addition, the four basic arithmetic operations and memory calculations can be carried out using the sexagesimal system. 2 SCIENTIFIC CALCULATIONS · Press @ m 0 to select the normal mode. · In each example, press ª to clear the display. [. . . ] Depth error (Error 3): · The available number of buffers was exceeded. (There are 8 buffers* for numeric values and 16 buffers for calculation instructions). *4 buffers in STAT and the complex number mode. Equation too long (Error 4): · The equation exceeded its maximum input buffer (142 characters). An equation must be shorter than 142 characters. M ? COMPLEX NUMBER CALCULATIONS (17) Random Numbers A pseudo-random number with three significant digits can be generated by pressing @ ` =. To generate the next random number, press =. You can perform this function in the normal and statistics modes. (You cannot perform this function while you are using the N-Base function. ) · Random numbers use memory Y. Each random number is generated on the basis of the value stored in memory Y (pseudorandom number series). i : Indicates an imaginary number is being displayed in the complex calculation mode. 1Rectangular 2Polar To carry out addition, subtraction, multiplication, and division using complex numbers, press @m1 to select the complex number mode. There are two modes of expression of the results of complex number calculations. (xy appears on the display. ) 2 coordinate mode. Be sure to observe the following handling rules: · Replace both batteries at the same time. · Do not mix new and old batteries. · Make sure the new batteries are the correct type. · When installing, orient each battery properly as indicated in the calculator. [Temporary memories (A-D, X and Y)] A stored value can be recalled as a value or variable for the use in equations. · In case you store an infinite decimal in the memory, recall it as a variable to obtain accurate answers. Ex. ) 1/3OY 3*RY= 3*@KY= (0. 3333. . . is stored to Y) To solve simultaneous linear equations with three unknowns, press @m2 to select the 3-VLE mode. Simultaneous Linear Equations with Three Unknowns: a1x + b1y + c1z = d1 a2x + b2y + c2z = d2 a3x + b3y + c3z = d3 Notes: D= a1 b1 c1 a2 b2 c2 a3 b3 c3 0. 999999999 1. · If the determinant D = 0, an error occurs. · If the absolute value of an intermediate result or calculation result is 1 × 10100 or more, an error occurs. When to Replace the Batteries If the display has poor contrast or nothing appears on the display even when ª is pressed in dim lighting, it is time to replace the batteries. Editing the Equation · Press < or > to move the cursor. You can also return to the equation after getting an answer by pressing > (<). See below for Multi-line playback function. · If you need to delete a number, move the cursor to the number you wish to delete then press d. [. . . ] Statistic mode (STAT): @m3 Used to perform statistical calculations. When executing mode selection, temporary memories, statistical data and last answer memory will be cleared even when reselecting the same mode. This calculator performs arithmetic operations and memory calculations using a fraction, and conversion between a decimal number and a fraction. · In all cases, a total of up to 10 digits including integer, numerator, denominator and the symbol (l) can be entered. · If the number of digits to be displayed is greater than 10, the number is converted to and displayed as a decimal number.
