User manual SHARP EL-520WG

[. . . ] ENGLISH HYP SCIENTIFIC CALCULATOR MODEL : Indicates that h has been pressed and the hyperbolic functions are enabled. If @H are pressed, the symbols "2ndF HYP" appear, indicating that inverse hyperbolic functions are enabled. ALPHA : Appears when K (STAT VAR), O or R is pressed. EL-520WG FIX/SCI/ENG: Indicates the notation used to display a value. DEG/RAD/GRAD: Indicates angular units. STAT OPERATION MANUAL PRINTED IN CHINA / IMPRIMÉ EN CHINE / IMPRESO EN CHINA 04LGK (TINSE0805EHZZ) · To edit an equation after recalling it, press > (<). · The multi-line memory is cleared by the following operations: @c, @F (including the Automatic Power Off feature), mode change, memory clear (@), RESET, @ `, K (R) ?, constant calculation, chain calculation, angle unit conversion, coordinate conversion, N-base conversion, numerical value storage to the temporary memories and independent memory. : Appears when statistics mode is selected. [. . . ] · When installing, orient each battery properly as indicated in the calculator. · Batteries are factory-installed before shipment, and may be exhausted before they reach the service life stated in the specifications. Notes on erasure of memory contents When the battery is replaced, the memory contents are erased. Erasure can also occur if the calculator is defective or when it is repaired. Make a note of all important memory contents in case accidental erasure occurs. 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 2 (QUAD) : Quadratic regression calculation The following statistics can be obtained for each statistical calculation (refer to the table below): Single-variable statistical calculation Statistics of Q and value of the normal probability function 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´) 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. 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. 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. Exponential regression, Logarithmic regression, Power regression, and Inverse regression calculation Statistics of Q and W. In addition, estimate of y for a given x and estimate of x for a given y. (Since the calculator converts each formula into a linear regression formula before actual calculation takes place, it obtains all statistics, except coefficients a and b, from converted data rather than entered data. ) Cautions COMPLEX NUMBER CALCULATIONS To carry out addition, subtraction, multiplication, and division using complex numbers, press m2 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. ) · Fluid from a leaking battery accidentally entering an eye could result in serious injury. Should this occur, wash with clean water and immediately consult a doctor. · Should fluid from a leaking battery come in contact with your skin or clothes, immediately wash with clean water. · If the product is not to be used for some time, to avoid damage to the unit from leaking batteries, remove them and store in a safe place. · Do not leave exhausted batteries inside the product. · Do not fit partially used batteries, and be sure not to mix batteries of different types. · Keep batteries out of the reach of children. · Exhausted batteries left in the calculator may leak and damage the calculator. · Explosion risk may be caused by incorrect handling. · Do not throw batteries into a fire as they may explode. Quadratic regression calculation Statistics of Q and W and coefficients a, b, c in the quadratic regression formula (y = a + bx + cx2). (For quadratic regression calculations, no correlation coefficient (r) can be obtained. ) When there are two x´ values, press @. When performing calculations using a, b and c, only one numeric value can be held. [. . . ] Ez a készülék megfelel a 89/336/EGK sz.
