Let π(x) be the number of primes less than or equal to the positive real number x. The asymptotic behaviour of this function had already interested the young Gauss. As a result of computing its value up to the
Finding Number of PrimesUsing an approximation theorem from Mathematics we find the approximate number of prime numbers less than a large number N. The approximation uses the natural logarithm function. Answer and Explanation: Become a member and unlock all Study Answers Start today. Try it now ...

* The prime number theorem says that the proportion of primes less than x is asymptotic to 1/ln x (in other words, as x gets very large, the likelihood that a number less than x is prime is inversely proportional to the number of digits in x). ...
For a perfect square , or 1 for all odd primes where is the Legendre symbol. A number that is not a perfect square but that satisfies this relationship is called a pseudosquare. In a Ramanujan conference talk, W. Gosper conjectured that every sum of four distinct odd squares is the su...
among integers), there are methods and algorithms to determine if a number is prime. One of the most famous is the Sieve of Eratosthenes. This ancient algorithm is used to find all primes up to a specified integer. It works by iteratively marking the multiples of each prime, starting from...
The second conjecture is actually a consequence of the first, and in 1937 Vinogradoff proved that any odd number that is sufficiently large is the sum of three odd primes. How large the number has to be is not known. It has been established that if N is an even integer larger than ee1...
In the interior of the cavities, the isotherms become parallel to the horizontal walls, indicating enhanced convection with the Grashof numbers. As the Hartmann number increases, the isotherms become less clustered along the hot wall and parallel to the vertical wall, indicating the reduction of ...
ait helps get them to marshal their resources to cope with an oncoming deadline (Chissom & IranNejad, 1992; Tice & Baumeister, 1997).However, if procrastination is irrational as well as representative of low conscientiousness,this “last-ditch” effort should tend to be less successful than ...
