  SRINIVASA RAMANUJAN He was born on 22naof December 1887 in a small village of Tanjore district, Madras.He failed in English in Intermediate, so his formal studies were stopped but his self-study of mathematics continued.  He sent a set of 120 theorems to Professor Hardy of Cambridge. As a result he invited Ramanujan to England.  Ramanujan showed that any big number can be written as sum of not more than four prime numbers.  He showed that how to divide the number into two or more squares or cubes.  when Mr. Litlewood came to see Ramanujan in taxi number 1729, Ramanujan said that 1729 is the smallest number which can be written in the form of sum of cubes of two numbers in two ways,i.e. 1729 = 93 + 103 = 13 + 123since then the number 1729 is called Ramanujan’s number.

  ARYABHATTA  Aryabhattawas born in 476A.D in Kusumpur, India.  He was the first person to say that Earth is spherical and it revolves around the sun.  He gave the formula (a + b)2 = a2 + b2 + 2ab  He taught the method of solving the following problems: 14 + 24 + 34 + 44 + 54 + …………+ n4 = n(n+1) (2n+1) (3n2+3n-1)/30

  BHASKARACHARYA  Hewas born in a village of Mysore district.  He was the first to give that any number divided by 0 gives infinity (00).  He has written a lot about zero, surds, permutation and combination.  He wrote, “The hundredth part of the circumference of a circle seems to be straight. Our earth is a big sphere and that’s why it appears to be flat.”  He gave the formulae like sin(A ± B) = sinA.cosB ± cosA.sinB

  BRAHMA GUPTA Brahma Gupta was born in 598A.D in Pakistan.  He gave four methods of multiplication.  He gave the following formula, used in G.P series  a + ar + ar2 + ar3 +……….. + arn-1 = (arn-1) ÷ (r – 1)  He gave the following formulae :  Area of a cyclic quadrilateral with side a, b, c, d= √(s -a)(s- b)(s -c)(s- d) where 2s = a + b + c + d

  MAHAVIRA Mahavira wasa 9th-century Indian mathematician from Gulbarga who asserted that the square root of a negative number did not exist. He gave the sum of a series whose terms are squares of an arithmetical progression and empirical rules for area and perimeter of an ellipse. He was patronised by the great Rashtrakuta king Amoghavarsha. Mahavira was the author of Ganit Saar Sangraha. He separated Astrology from Mathematics. He expounded on the same subjects on which Aryabhata and Brahmagupta contended, but he expressed them more clearly. He is highly respected among Indian Mathematicians, because of his establishment of terminology for concepts such as equilateral, and isosceles triangle; rhombus; circle and semicircle. Mahavira’s eminence spread in all South India and his books proved

  SHAKUNTALA DEVI She was born in 1939  In 1980, she gave the product of two, thirteen digit numbers within 28 seconds, many countries have invited her to demonstrate her extraordinary talent.  In Dallas she competed with a computer to see who give the cube root of 188138517 faster, she won. At university of USA she was asked to give the 23rdroot of91674867692003915809866092758538016248310668014430862240712 6516427934657040867096593279205767480806790022783016354924852 3803357453169351119035965775473400756818688305620821016129132 845564895780158806771.She answered in 50seconds. The answer is 546372891. It took a UNIVAC 1108 computer, full one minute (10 seconds more) to confirm that she was right after it was fed with 13000 instructions.Now she is known to be Human Computer.
