1) Composed c.1500 CE in kerala,Tantrasamgraha is an astronomical treatise took world trigonometry to new heights
2)It discusses all aspects of mathematical astronomy such as
longitudes and latitudes of planets diurnal problems,eclipses,visibility,time
longitudes and latitudes of planets diurnal problems,eclipses,visibility,time
3) Tantrasamgraha was the first work in the world to define trigonometric functions in terms of right angles rather than circles.
4)The work deduces 1000 odd trigonometrical identities most of which are valid to this day
5) The tantrasamgraha-vakhya gives the derivations for arc sine, arc cos and arc tan
7)Tantrasamgraha-vakhya was the first work in the world to derive and use power series
8)The origin of calculus is traced to Nilakanta Somayaji and his school
9)"Priority of Keralese in calculus over Netwon and Leibnitz is now beyond doubt"-Paul Ernest, Math historian(2011)
10)Recently, historians have found evidence that knowledge of kerala school of Mathematics was transmitted to Europe
11) it is also interesting to note that during this period Kerala was one of the very few regions which were not under Islamic rule
12) Also interesting to note that vast regions of India ruled by indo-Islamic dynasties failed to produce anything resembling these works
@dumroobaje Nope :(. But they built harems
@fcukPC_ Thank you :)
