These are functions of arcs of circles and not functions of angles. Jyā and koti-jyā are closely related to the modern trigonometric functions of sine and cosine. In fact, the origins of the modern terms of "sine" and "cosine" have been traced back to the Sanskrit words jyā and koti-jyā. [1]
The Bhagavad Gita (/ ˈ b ʌ ɡ ə v ə d ˈ ɡ iː t ɑː /; [1] Sanskrit: भगवद्गीता, IPA: [ˌbʱɐɡɐʋɐd ˈɡiːtɑː], romanized: bhagavad-gītā, lit. 'God's song'), [a] often referred to as the Gita (IAST: gītā), is a Hindu scripture, dated to the second or first century BCE, [7] which forms part of the epic Mahabharata.
In mathematics, sine and cosine are trigonometric functions of an angle.The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse), and the cosine is the ratio of the length of the adjacent leg to that ...
These endeavors culminated in the eventual discovery of the power series expansions of the sine and cosine functions by Madhava of Sangamagrama (c. 1350 – c. 1425), the founder of the Kerala school of astronomy and mathematics, and the tabulation of a sine table by Madhava with values accurate to seven or eight decimal places.
The Bible [1] is a collection of religious texts or scriptures which to a certain degree are held to be sacred in Christianity, Judaism, Samaritanism, Islam, the Baháʼí Faith, and other Abrahamic religions. The Bible is an anthology (a compilation of texts of a variety of forms) originally written in Hebrew, Aramaic, and Koine Greek. The ...

The number of childfree women is at a record high: 48 percent of women between the ages of 18 and 44 don’t have kids, according to 2014 Census numbers. The Huffington Post and YouGov asked 124 women why they choose to be childfree.
[27] [28] Using the Taylor series approximations of sine and cosine, he produced a sine table to 12 decimal places of accuracy and a cosine table to 9 decimal places of accuracy. He also gave the power series of π and the angle , radius , diameter , and circumference of a circle in terms of trigonometric functions.
