15th century peaceful part of India discovery.

  • Leibniz formula for pi The Leibniz formula for pi was derived in the early part of the 15th century by Madhava of Sangamagrama (c. 1340-1425 CE), an Indian mathematician and founder of the Kerala school of astronomy and mathematics over 200 years before Leibniz.[194][195]
  • Mean value theorem: An early version of this calculus theorem was first described by Parameshvara (1370–1460) from the Kerala school of astronomy and mathematics in his commentaries on Govindasvāmi and Bhāskara II.[196]
  • Pi, infinite series: The infinite series for π is attributed to Madhava of Sangamagrama (c. 1340-1425) and his Kerala school of astronomy and mathematics.[201][202] He made use of the series expansion of arctanx to obtain an infinite series expression, now known as the Madhava-Gregory series, for π.[201] Their rational approximation of the error for the finite sum of their series are of particular interest. They manipulated the error term to derive a faster converging series for π.[164]They used the improved series to derive a rational expression,[164]104348 / 33215 for π correct up to eleven decimal places, i.e.3.14159265359.[194][195]
  • Taylor-Maclaurin series: In the 14th century, the earliest examples of the Taylor-Maclaurin series were first given by Madhava of Sangamagrama and his successors at the Kerala school of astronomy and mathematics. They found a number of special cases of the Taylor series, including those for the trigonometric functions of sine, cosine, tangent, andarctangent. They also found the second-order Taylor approximations for these functions, and the third-order Taylor approximation for sine.[207][208][209]

@arp2041
I got an email saying u had mentioned me on some thread but when I came online it was gone.
