In India, mobile numbers (including pagers) on GSM, WCDMA, LTE and NR networks start with either 9, 8, 7 or 6.Each telecom circle is allowed to have multiple private operators; earlier it was two private + BSNL/MTNL, subsequently it changed to three private + BSNL/MTNL in GSM; now each telecom circle has all four operators including Reliance Jio, Bharti Airtel, Vodafone idea ltd and BSNL/MTNL.
A total of seven chess players have been the chess world number one on the official FIDE rating list since it was first published in July 1971. [1] The first world number one, in July 1971, was Bobby Fischer. In January 1976 Anatoly Karpov became the highest-rated player on the FIDE list, FIDE having dropped Fischer (whose rating was higher ...
Continuing this process yields an infinite sequence of nested intervals, labeled by an infinite sequence of digits , , , ..., and one writes =. …. In this formalism, the identities 1 = 0.999... and 1 = 1.000... reflect, respectively, the fact that 1 lies in both [0, 1] . and [1, 2] , so one can choose either subinterval ...
In mathematics, the inverse trigonometric functions (occasionally also called arcus functions, [1][2][3][4][5] antitrigonometric functions[6] or cyclometric functions[7][8][9]) are the inverse functions of the trigonometric functions, under suitably restricted domains. Specifically, they are the inverses of the sine, cosine, tangent, cotangent ...
Newton's method is one of many known methods of computing square roots. Given a positive number a, the problem of finding a number x such that x2 = a is equivalent to finding a root of the function f(x) = x2 − a. The Newton iteration defined by this function is given by.
Noncommutative algebra. v. t. e. In mathematics, an algebraic number field (or simply number field) is an extension field of the field of rational numbers such that the field extension has finite degree (and hence is an algebraic field extension). Thus is a field that contains and has finite dimension when considered as a vector space over .
The Basel problem is a problem in mathematical analysis with relevance to number theory, concerning an infinite sum of inverse squares. It was first posed by Pietro Mengoli in 1650 and solved by Leonhard Euler in 1734, [1] and read on 5 December 1735 in The Saint Petersburg Academy of Sciences. [2] Since the problem had withstood the attacks of ...
