The solution to partial fraction was known to the Rigvedic People as states in the purush Sukta (RV 10.90.4): With three-fourths Puruṣa went up: one-fourth of him again was here. The Satapatha Brahmana (c. 7th century BCE) contains rules for ritual geometric constructions that are similar to the Sulba Sutras. [22]
This follows the use of unit fractions in Indian mathematics in the Vedic period, and the Śulba Sūtras' giving an approximation of √ 2 equivalent to + +. [ 14 ] In the Gaṇita-sāra-saṅgraha (GSS), the second section of the chapter on arithmetic is named kalā-savarṇa-vyavahāra (lit. "the operation of the reduction of fractions").
Decimal fractions can also be expressed using scientific notation with negative exponents, such as 6.023 × 10 −7, a convenient alternative to the unwieldy 0.0000006023. The 10 −7 represents a denominator of 10 7. Dividing by 10 7 moves the decimal point seven places to the left.
In summary, every real number that is not a decimal fraction has a unique infinite decimal expansion. Each decimal fraction has exactly two infinite decimal expansions, one containing only 0s after some place, which is obtained by the above definition of [x] n, and the other containing only 9s after some place, which is obtained by defining [x ...
The Hindu–Arabic system is designed for positional notation in a decimal system. In a more developed form, positional notation also uses a decimal marker (at first a mark over the ones digit but now more commonly a decimal point or a decimal comma which separates the ones place from the tenths place), and also a symbol for "these digits recur ad infinitum".
The program was renamed to National Talent Search Scheme with the NTSE examination now being conducted for classes X, XI, and XII. Currently, the NTSE exam is conducted only for 10th class students in India in two phases with subjects relating to Mental Ability Test and Scholastic Aptitude Test (SAT) for 100 marks each. [6] [7]
Math anxiety can develop due to various factors such as parental and teacher attitudes, social stereotypes, and personal traits. Help to counteract the anxiety can come from changes in instructional approaches, by interactions with parents and teachers, and by tailored treatments for the individual.
Brahmagupta was not able to apply his solution uniformly for all possible values of N, rather he was only able to show that if x 2 − Ny 2 = k has an integer solution for k = ±1, ±2, or ±4, then x 2 − Ny 2 = 1 has a solution. The solution of the general Pell's equation would have to wait for Bhāskara II in c. 1150 CE. [29]
