The document presents a new interpretation of a rule in the Ganita-siira-sa4graha (GSS), an ancient Indian mathematics text, for calculating the surface area of a spherical segment.
Previous interpretations by Rangacharya and Jain assumed the rule treated the spherical segment as a flat circular base. The document suggests an alternate interpretation where the Sanskrit term "viskambha" refers to the curvilinear breadth of the segment, not its diameter. This new interpretation matches the true mathematical formula and has less error than the previous views.
This document discusses ancient Indian values of Pi that were used in mathematics. It provides 5 ancient approximations of Pi that were used in India and other parts of the world:
1. The simplest approximation of Pi = 3, which was used by the ancient Babylonians, in the Bible, and in ancient Chinese works. Similar approximations are found in ancient Indian texts.
2. The "Jaina value" of Pi = 22/7, which was frequently used in Jain texts and first appeared in India around the 1st century AD.
3. The Archimedean value of Pi = 22/7, which was recognized as a satisfactory approximation after Archimedes showed Pi is between 3 1/
1. According to Jaina cosmography, the Jambu Island is circular with a diameter of 100,000 yojanas.
2. Ancient Jaina texts provided approximations for the circumference of the Jambu Island using simple formulas like C=3D. More accurate values were also calculated using the formula C=√(10D2) which is better than C=3D.
3. The article examines various circumference values found in ancient Jaina texts like the Tiloya-Pannatti and expresses them using the detailed unit system from the text to compare to the precise modern calculation of the circumference.
1) The ancient Indian mathematician Bhaskara II first described the addition and subtraction theorems for sines in his work Jyotpatti from 1150 AD. These theorems state that the sine of the sum of two arcs is equal to the sum of the sines of individual arcs multiplied by their cosines, and the sine of the difference of two arcs is equal to the difference of the sines.
2) Bhaskara II provided two formulas based on these theorems to tabulate sines at intervals of 225 minutes and 60 minutes. These formulas allow constructing tables of 24 sines and 90 sines respectively using recurrence relations.
3) The article discusses Bhaskara II's contribution to trigon
1) Brahmagupta, an ancient Indian mathematician from the 7th century AD, developed formulas for calculating the area and diagonals of a cyclic quadrilateral using only the lengths of its four sides.
2) His formula for accurate area involved taking the square root of the product of terms involving the differences between half sums of opposite sides.
3) His expressions for the diagonals involved dividing and multiplying terms involving products of the sides, and took the square root of the results. These formulas are considered some of the most remarkable in Hindu geometry.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help boost feelings of calmness, happiness and focus.
1. Madhava of Sangamagrama formulated a rule equivalent to the Gregory series for calculating the inverse tangent function.
2. The rule expresses the inverse tangent as a sum of terms involving sines and cosines, equivalent to the Gregory series.
3. Ancient Indian mathematicians provided proofs of the rule, equivalent to modern proofs through term-by-term integration, showing they understood the concept of infinite series well before Western mathematicians formulated them explicitly.
Bhaskara II, an Indian mathematician from the 12th century, derived the formula for the surface area of a sphere. He used a crude form of integration by dividing the surface into thin circular sections and approximating their areas. This led to the formula of circumference x diameter. Earlier, Aryabhata II had provided the same formula, though Bhaskara criticized another mathematician, Lalla, for providing an incorrect formula. Bhaskara's derivation showed originality compared to Archimedes' method, though it lacked the same level of ingenuity.
1) The ancient Indian text Baudhayana's Sulba Sutra from around 800-400 BC contains a rule for approximating the square root of two. The rule increases the side of a square by one-third and one-fourth parts to get an approximation of 1.41421.
2) This approximation method of linear interpolation was popular in ancient India. The rule can be explained through a two-term interpolation formula.
3) Repeated use of this interpolation process yields the four-term approximation found in the Sulba Sutra, equivalent to methods used by later mathematicians like Neugebauer. While an improvement, the Indian approximation was still less accurate than the sexagesimal
1) Ancient Indian mathematicians developed rational approximations to trigonometric functions like sine, cosine, and versine that were found in Sanskrit works from the 7th to 17th centuries AD.
2) These approximations took the form of algebraic formulas relating the functions to angles in degrees. For example, one approximation for sine was sin(A) ≈ 16A(180-A)/(32400-A^2).
3) These formulas, which were popular in India, can be found in many original Indian mathematical works and show that such approximations were well-established by the 7th century.
1) Neelakantha Somaydji was an important mathematician from medieval India who lived from 1443-1543 AD and wrote several astronomical works.
2) In one of his works called Golasara, Neelakantha provides a formula for computing the length of a small circular arc given the Indian Sine and Versed Sine.
3) The formula, which is equivalent to the modern formula, enables the approximate computation of an angle when its sine or cosine is given.
1. The property that the second order differences of sines are proportional to the sines themselves was known in early Indian mathematics, dating back to Aryabhata I in the 5th century AD.
2. The paper describes various formulations of this proportionality found in important Indian astronomical works from the 5th to 15th centuries. It also outlines Nilakantha Somayaji's ingenious geometric proof of the property from his commentary on Aryabhatiya in the early 16th century.
3. The Indian mathematical method of computing sine tables using this difference property, which involves an implied differential process, was considered novel by Western scholars despite being used in India since ancient times
This document discusses fractional parts of Aryabhata's sine differences that are found in Govindasvami's commentary on Mahabhashya. Specifically:
1. Govindasvami's commentary provides the sexagesimal fractional parts (seconds and thirds) of Aryabhata's 24 tabular sine differences, allowing for a more accurate sine table with values given to the second order of sexagesimal fractions.
2. These fractional parts found in Govindasvami's commentary are subtracted from or added to Aryabhata's sine differences to improve the accuracy of the table.
3. In addition to improving Aryabhata's sine table, the
