Actually Madhava of Sangamagrama (now cochin suburb) in 1350 wrote extensively on the sine, cosine, tangent and arctangent functions and the value of Pie. He explained the traditional algebric concept of finite processes to include infinite series.
The infinite series is what we traditionally know as Integration and Differentiation. He also connected the infinite series with geometry and trigonometry, which are today the foundation of calculus.
He demonstrated that, by successively adding and subtracting different odd number fractions to infinity, he could arrive in on an exact formula for pie (this was two centuries before Leibniz was to come to the same conclusion in Europe). Through his application of this series, Madhava obtained a value for π correct to an astonishing 13 decimal places !!
Madhava went on to use the same mathematics to obtain infinite series expressions for the sine formula, which could then be used to calculate the sine of any angle to any degree of accuracy, as well as for other trigonometric functions like cosine, tangent and arctangent. Perhaps even more remarkable, though, is that he also gave estimates of the error term or correction term, implying that he quite understood the limit nature of the infinite series.
In astronomy, he discovered a procedure to determine the positions of the Moon every 36 minutes, and methods to estimate the motions of the planets.
Now Madhava was not the first Kerla mathematician, but he was the most famous. However he was a student of Indian mathematics and studied mathamatical works by Sankaranarayana (866 AD) who first defined algebra and Euclidean algorithm, which he called kuttakara ("pulveriser"). Sankaranarayana himself only expanded on the work of Aryabhata (480 AD) which included trigonometry and algebra. Aryabhata published work on indeterminate equations and calculations of summation of series of squares and cubes.
Even today diophantine equations which are used in cryptology is solved using something called Aryabhata algorithm.
Common don't bring religion into this...
Well I do appreciate that he still considers India to be his mother country, however on the other hand he has time to spare some BS on the very same country...
Why not ? He is a muslim .....if his actions bring shame on Muslims then he should be more careful...don't you agree?
In any case his disconnect from his root and culture has everything to do with his muslim identity and background that did not provide him with an opportunity to learn about it.
It may very well be the root of his problem.
What culture are you part of anyways, the kind of low self esteem and identity crisis you are displaying here, it can only be associated with one "culture". No prizes for guessing which one.
