[. . . ] 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. And if the FIX, SCI, or ENG indicator is displayed, clear the indicator by pressing @ f. Coordinate Conversions · Before performing a calculation, select the angular unit. Y y 0 x X P (x, y) (12) Y P (r, ) r INTRODUCTION About operation examples, please refer to the attached sheet. [. . . ] · The calculation ranges were exceeded while performing calculations. Depth error (Error 3): · The available number of buffers was exceeded. (There are 8 buffers* for numeric values and 16 buffers for calculation instructions). 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 @ ` =. (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. Be sure to observe the following handling rules: · Replace both batteries at the same time. · 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 > (<). · If you need to delete a number, move the cursor to the number you wish to delete then press d. · If you need to insert a number, move the cursor to the place immediately after where you wish to insert the number then enter the number. [Independent memory (M)] In addition to all the features of temporary memories, a value can be added to or subtracted from an existing memory value. [Last answer memory (ANS)] The calculation result obtained by pressing = or any other calculation ending instruction is automatically stored in the last answer memory. [Formula memories (F1 and F2)] : available only on EL-506V Formulas up to 80 characters each can be stored. As with storing numerical values in the memory, storing a new equation will automatically replace any existing equation in memory without notification. [. . . ] 2) Fraction Calculations (9) INITIAL SETUP Mode Selection Normal mode (NORMAL): @m0 Used to perform arithmetic operations and function calculations. Complex number mode (CPLX): @m1 Used to perform arithmetic operations with complex numbers. 3-VLE mode (3-VLE): @m2 Used to perform simultaneous linear equations with three unknowns. 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. [. . . ]
