How do I find my taxicab number?
The nth Taxicab number Taxicab(n), also called the n-th Hardy-Ramanujan number, is defined as the smallest number that can be expressed as a sum of two positive cube numbers in n distinct ways. The most famous taxicab number is 1729 = Taxicab(2) = (1 ^ 3) + (12 ^ 3) = (9 ^ 3) + (10 ^ 3).
How many taxicab numbers are there?
Sloane defines a slightly different type of taxicab numbers, namely numbers which are sums of two cubes in two or more ways, the first few of which are 1729, 4104, 13832, 20683, 32832, 39312, 40033, 46683, 64232, (OEIS A001235).
What is the second taxicab number?
The taxicab numbers subsequent to 1729 were found with the help of computers. John Leech obtained Ta(3) in 1957. E. Rosenstiel, J. A. Dardis and C. R. Rosenstiel found Ta(4) in 1989.
What was interesting about the taxicab number?
1729
Ramanujan quickly pointed out that no Mr. Hardy, 1729 was indeed interesting . he said it is the smallest number that can be expressed as a sum of two cubes in two different ways. 2.1- Fermate’s last theorem: we cannot separate a cube as a sum of two cubes.
What is the use of taxicab numbers?
A taxicab number is the name given by mathematicians to a sequence of special numbers: 2, 1729 etc. A taxicab number is the smallest number that can be expressed as the sum of two positive cubes in n distinct ways.
Where can I find Ramanujan number?
Ramanujan Numbers are the numbers that can be expressed as sum of two cubes in two different ways. Therefore, Ramanujan Number (N) = a3 + b3 = c3 + d3.
Why is 2 a taxicab number?
What is taxicab geometry used for?
Taxicab geometry can be used to assess the differences in discrete frequency distributions. For example, in RNA splicing positional distributions of hexamers, which plot the probability of each hexamer appearing at each given nucleotide near a splice site, can be compared with L1-distance.
What is Ramanujan number?
It’s the smallest number expressible as the sum of two cubes in two different ways.” Because of this incident, 1729 is now known as the Ramanujan-Hardy number. To date, only six taxi-cab numbers have been discovered that share the properties of 1729.
What is Srinivasa Ramanujan number?
1729 is the natural number following 1728 and preceding 1730. It is a taxicab number, and is variously known as Ramanujan’s number and the Ramanujan-Hardy number, after an anecdote of the British mathematician G. H. Hardy when he visited Indian mathematician Srinivasa Ramanujan in hospital.
How do I find my taxicab distance?
In Taxicab Geometry, the distance between two points is found by adding the vertical and horizontal distance together.
