10/19/11 Vedic Mathematics Contributions of Hindu Mathematicians of Ancient Times! What are Vedas? • Veda means wisdom, knowledge or vision • The laws of the four Vedas regulate the social, legal, domestic and religious customs of the Hindus to present day • As the ancient Hindus seldom kept any historical record of their religious, literary and political realization, it is difficult to determine the period of the Vedas with precision. • Compositions of the Vedas were handed down through generations by the word of mouth. • The Vedas were mainly compiled around (c. 1500 BC) 1 10/19/11 What is Vedic Mathematics? • Ancient system of Mathematics which was rediscovered from the Vedas. • It is a unique technique of calculations based on simple principles and rules, with which any mathematical problem involving algebra, arithmetic, geometry and trigonometry can be solved mentally. • It is based on 16 simple mathematical formulae or Sutras (and 13 sub-formulae or sub sutras) from the Uup-Veda Sthapatya Veda of Atharva Vedas as discovered by Sri Bharati Krishna Tirthaji. (1884 - 1960) What does Mathematics have to do with Hinduism? Just as the feathers of a peacock and the jewel-stone of a snake are placed at the highest point of the body, so is the position of mathematics the highest amongst all branches of the Vedas and the Shastras. The mantra at the end of the annahoma invokes powers of ten from a hundred to a trillion. Hail to śata (102), sahasra (103), ayuta (104), niyuta (105), prayuta (106), arbuda (107), nyarbuda (108), samudra (109), madhya (1010), anta (1011), parārdha (1012), the dawn (uśas), the twilight (vyuṣṭi), the one which is going to rise (udeṣyat), the one which is rising (udyat), the one which has just risen (udita), the heaven (svarga), the world (loka) and all. 2 10/19/11 The sutras list the rules of the sacrificial fire altars: Most mathematical problems considered spring from a single theological requirement: a) When constructing fire altars of different shapes, the altars should occupy the same area. b) The altars were required to be constructed of five layers of burnt brick, with the further condition that each layer consist of 200 bricks and that no two adjacent layers have congruent arrangements of bricks. “The diagonal rope of an oblong rectangle produces both which the flank and the horizontal ropes produce separately” 16 Sutras (formulae) 3 10/19/11 1. Ekādhikena Pūrvena means:“By one more than the previous one”. It is used in 'Squaring of numbers ending in 5' Vedic Method 65 X 65 = 4225 (multiply the previous digit 6 by one more than itself 7. Then write 25 ) Conventional Method: 65 X65 325 +3 9 0 0 4225 2. Nikhilam Navatas' Chandmam Dasatah “all from 9 and the last from 10” This formula can be very effectively applied in multiplication of numbers, which are nearer to bases like 10, 100, 1000 i.e., to the powers of 10 Conventional Method 97 103 X94 X105 388 515 +8 7 3 0 0000 9, 1 1 8 +1 0 3 0 0 1 0, 8 1 5 4 10/19/11 3. Urdhva Tiryagbhyam “Vertically and cross wise” 75 X 32 Step 1: 5×2=10, write down 0 and carry 1 Step 2: 7×2 + 5×3 = 14+15=29, add to it previous carry over value 1, so we have 30, now write down 0 and carry 3 Step 3: 7×3=21, add previous carry over value of 3 to get 24, write it down. So we have 2400 as the answer. Multiplication of Numbers with 3 digits 103 X 105 Step 1: 3 x 5 = 15 Retain 5 carry over 1 Step 2: 5 x 0 + 0 x 3 = 0 Add carried over 1 and retain Step 3: 5 x 1 + 0 x 0 + 1 x 3 = 8 Retain 8 Step 4: 0 x 1 + 1 x 0 = 0 Retain 0 Step 5: 1 x 1 = 1 Combining the numbers we get: 10815 5 10/19/11 Example: 45x – 23y = 113 23x – 45y = 91 Gunita Samuccayah – Samuccayah Gunitah 'the product of the sum' This is used to factorize homogeneous equations of second degree in three variables x, y and z. Example : 3x 2 + 7xy + 2y 2+ 11xz + 7yz + 6z 2 Eliminate z and retain x, y ; factorize 3x 2 + 7xy + 2y 2 = (3x + y) (x + 2y) Eliminate y and retain x, z; factorize 3x 2 + 11xz + 6z 2 = (3x + 2z) (x + 3z) Explanation Eliminate z by putting z = 0 and retain x and y and factorize the obtained quadratic in x and y Similarly eliminate y and retain x and z and factorize the quadratic in x and z. Fill the gaps thus With these two sets of factors, fill in the factors are: the (3x + y + 2z) (x + 2y + 3z) gaps caused by the elimination process of z and y respectively. This gives 6 10/19/11 Some Famous Indian Mathematicians and their contributions. Aryabhatta (475 A.D. -550 A.D.) - laid the foundations of algebra - gave the value of pi as 3.1416, claiming, for the first time, that it was an approximation. He gave it in the form that the approximate circumference of a circle of diameter 20000 is 62832. - gave methods for extracting square roots, summing arithmetic series, solving indeterminate equations of the type ax - by = c, and also gave what later came to be known as the table of Sines. Brahmagupta (598 A.D. -665 A.D.) - introduced negative numbers and operations of zero in arithmetic - formulated the rule of three and proposed rules for the solution of quadratic and simultaneous equations. - the formula for the area of a cyclic quadrilateral as where s is the semi perimeter. - was the first mathematician to treat algebra and arithmetic as two different branches of mathematics. - gave the solution of the indeterminate equation Nx² + 1 = y². - He is also the founder of Numerical Analysis. 7 10/19/11 Bhaskara (1114 A.D. -1185 A.D.)/ Bhaskaracharaya - was the first to declare that any number divided by zero is infinity and that the sum of any number and infinity is also infinity - wrote Siddhanta Siromani (1150 A.D.). It is divided into four sections -Lilavati (a book on arithmetic), Bijaganita (algebra), Goladhayaya (chapter on sphere -celestial globe), and Grahaganita (mathematics of the planets) - introduced the cyclic method to solve algebraic equations. 6 centuries later, European mathematicians like Galois, Euler and Lagrange rediscovered this method and called it "inverse cyclic". - Bhaskara's works developed into differential calculus. He gave an example of what is now called "differential coefficient" and the basic idea of what is now called "Rolle's theorem". Unfortunately, later Indian mathematicians did not take any notice of this. 5 centuries later, Newton and Leibniz developed this subject Srinivasa Aaiyangar Ramanujan (1887-1920) - best known for his work on hypergeometric series and continued fractions. - In January 1913 Ramanujan sent some of his work to G. H. Hardy, Cayley lecturer in mathematics at Cambridge. Hardy noticed that whereas Ramanujan had rediscovered, and gone far beyond, some of the latest conclusions of Western mathematicians, he was completely ignorant of some of the most fundamental areas. 8 10/19/11 References Kandasamy, W.
