IEEE 260.3-1993 (R2006) pdf free.American National Standard Mathematical Signs and Symbols for Use in Physical Sciences and Technology.
IEEE 260.3 In general, this Standard favors the notation, definition, and meaning given in Reference 2 wherever disagreementexists with Reference 1.Since Reference 2 was published by the National Bureau of Standards 2 and is a standardreference, even for other references, it is appropriate that this Standard be consistent with Reference 2 except wheretype styles need to be modified to conform to the rules in Clause 3 of this Standard. Where an alternative sign orsymbol displayed in Reference I agrees with this Standard, the two Standards are assumed to be in accord. 3Thosesymbols in Reference 1 that belong to special fonts,violating the principles of Clause 3, are not included in thisStandard.
Some minor discrepancies between ISO and symbols of this Standard (ANS) exist for circular and hyperboliccotangents as well as their inverses (ISO 11-9;ANS, this Standard the cotangent functions aresymbolized by “ctn”to make them more distinguishable from “cos”than “cot”. Then each of the six basic three-lettersymbols has no more than one letter positionally in common with any of the other five. Also, the valid ranges in theprincipal values of the inverse secants and cosecants for negative arguments differ in the two Standards.
Two items in Reference 1, viz, ISO 11-11.3 and 11-13.4, use italic type, where, by the rules of Clause 3, roman typeis mandatory; qv ANS 9.8.4 and 9.7.1, respectively. The combinatorial symbol,ISO item 11-6.16, uses subscripts andsuperscripts for arguments, but to accommodate complicated literal values for them, an ordered pair is used in thisStandard, qv ANS
The symbol, >, in Reference 1 (11-4.3) has the meaning “contains the element”, but means “such that” in ANS(9.3.7)Although zero belongs to the set,N, in Reference 1 (11-4.9), in ANS(9.3.15) the set,N, consists only of the naturalnumbers, i.e. the positive integers, which does not include zero. The ISO symbol for equality by definition (11-5.3) islanguage dependent (cf ANS 9.2.16).The order of the arguments in the symbols for elliptic integrals as well as thesign of the characteristic,n, are different for the two Standards. Although the symbols used for polar, cylindrical, andspherical coordinates in Reference I are the same as those used in this Standard, the definitions of all of these symbols,except for z, disagree in the two documents (cf ISO 11-12,ANS 9.6.2).IEEE 260.3 pdf download.
