The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Gupta1975j
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.
Gupta1975f
This document summarizes a rule from the ancient Indian mathematics text Lilavati for computing the sides of regular polygons inscribed in a circle. The rule provides coefficients that when multiplied by the circle's diameter and divided by 12,000 yield the side lengths of triangles, squares, pentagons, etc. up to nonagons. While the rationales for some coefficients are clear, others are less accurate, possibly due to limitations in available sine tables or knowledge of exact solutions. The document discusses methods that may have been used to derive the coefficients and compares the original values to more accurate modern calculations.

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.
Gupta1974j
1) The document discusses an ancient Indian mathematics problem involving using gnomons (vertical rods) to measure the height of a lamp post and the distance between shadow tips.
2) It presents the original rule from the Aryabhatiya, and provides examples and explanations of how to use the rule to calculate heights and distances.
3) The rule involves using ratios between shadow lengths, distance between shadow tips, and gnomon length to determine the "upright" distance and lamp post height.
Gupta1974i
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.
Gupta1974g
The document summarizes rules for calculating the perimeter and area of an ellipse from an ancient Indian mathematics text from the 9th century AD. It provides the ancient text's approximate formulas for perimeter and area, and explains how they were likely empirically derived by comparing an ellipse to simpler shapes like a semicircle or circular segment. It also gives the correct elliptic integral formulas, and shows how the ancient approximations compare to the precise solutions for a numerical example.
Gupta1974f
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.
Gupta1974e
The document discusses addition and subtraction theorems for the sine and cosine functions in medieval Indian mathematics. It provides statements of the theorems as found in several important Indian works from the 12th to 17th centuries. These theorems are equivalent to the modern mathematical formulas for trigonometric addition and subtraction. The document also outlines various proofs and derivations of the theorems found in Indian works, which indicate how Indians understood the rationales behind the theorems.
Gupta1973f
Narayana Pandita, an important ancient Indian mathematician who lived in the 14th century, developed a method for approximating quadratic surds (square roots of non-perfect squares). His method involved finding integer solutions to the indeterminate equation x2 - Ny2 = 1 and taking the ratio of the solutions as the approximation. The article describes Narayana's method using the example of approximating √10 and relates his method to other ancient approaches like the binomial approximation and Newton's method. It highlights the significance of Narayana's works in the development of ancient Indian mathematics.

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.
Gupta1973d
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.
