Il valore assoluto si può indicare con un trattino sopra il carattere?

Answer 1

Il “trattino sopra” there is no single symbology, può indicates a varied mucchio di cose in the second part of the context.
If necessary, specifying the university faculty and the argument of the test, sarebbe più semplice restricte il campo.
Di solito non indicates the absolute value.
Potrebbe essere il simbolo per le classi di equivalenza nell’arithmetica modulare?
Questo spiegherebbe the presence of a “module” (which in this case is not synonymous with assoluto value).
It is the only case that I avenga in mente di trattino posto sopra un numero (and not solo una lettera).
Carry the continuous precision to believe that these are modular equations.
Fissato un number interon > 0 dici che due interi aeb sono “congruenti modulo n” if puoi scrivere a= b+ nk per un qualche intero k.
La classe congruenza modulo n di un numero a, oververo l’insieme di tutti i numeri b congruenti ads a modulo n, può essere indicata con “a” con una barretta sopra. (Questa notazione si USA soprattutto all’ inizio, per non ingenerare confusione tra un num e la sua class di equivalenza.).
Ad esempio modulo 2 tutti i numeri pari son congruenti tra loro (and puoi indicali with 0 con la barretta sopra) and tutti i numeri dispari son equivalenti tra loro (and puoi indicali with 1 con la barretta sopra). Module 2 (quindi con le barrette sopra i numeri) was written 1 + 1 = 2 = 0, indicating that the sum of the numeri disappearing due is a bet number.
ps: Ricordo is a physics note that puts the barrette sui tensori, un par ogni index (veto with a barretta, le matrici with due barrette, …) In any case, always delle lettere, non dei numeri.

answer 2

Normally the absolute value is indicated with a segni |, a prime and the altro dopo:|x|= absolute value di x;.
il segno sopra il carattere, in mathematics sta spesso ad indicates il valore medio.
If x1, x2, … …, xn sleep n misure di a certain property x (temperature, press, lunghezza, weight, …) with x (soprasegnato, this is the way to indicate the trattino sopra il carattere, but not saprei how to graphically represent what il trattino stesso, che ometto) if you intend to value it medio delle n misure eseguite.
Spero di essere stato useful (and di non avere violato “regole”)!
in good health.

answer 3

Talvolta si dice che x (contrattino sopra) is a constant function; and this US rating added to the analysis to indicate consistent quality (x, y, z.) associates the magari ad with a variable. Advertising example, y( x senza trattino) = x con trattino is a generic constant function, com potrebbe esserlo anche y = 2.
In the ogni case, it is said that bene chi afferma che il trattino has no precise meaning.

answer 4

il trattino sopra the number indicates a periodic number (s: 4,544444444 …) il valuee assoluto si indicates con” |” (en:|5 |

Answer 5

ma at difficult fare cosà ¬:|5|o|6|ecc?

Answer 6

Scusami ma non riesco a capire in che senso intenti, riesci a fare un esempio?

Answer 7
