Binary logarithm Wikipedia
In mathematics, the binary logarithm (log 2 n) is the power to which the number 2 must be raised to obtain the value is, for any real number x, = ⁡ =. For example, the binary logarithm of 1 is 0, the binary logarithm of 2 is 1, the binary logarithm of 4 is 2, and the binary logarithm of 32 is 5.. The binary logarithm is the logarithm to the base 2.

2^n n Numbers :
The major research on series of numbers like the Fermat numbers (2^{2^n} + 1) or the Mersenne numbers (2^n1) is done on finding prime numbers (numbers that their only divisors are 1 and the number itself, 1 is not prime number by definition) and primality testing for their members.

Apply that to the product \frac{n!}{2^n}\: =\: \frac{4!}{2^4} \frac{5}2 \frac{6}2 \frac{7}2\: \cdots\:\frac{n}2 This is a prototypical example of a proof employing multiplicative telescopy. Notice how much simpler the proof becomes after transforming into a form where the induction is obvious, namely: \: a product is >1 if all factors ...


Proof that T(n)=n(n+1)/2 University of Surrey
For the proof, we will count the number of dots in T(n) but, instead of summing the numbers 1, 2, 3, etc up to n we will find the total using only one multiplication and one division! To do this, we will fit two copies of a triangle of dots together, one red and an upsidedown copy in green. This ...

A proof that if 2 n 1 is prime, then so is n
Let a and n be integers greater than one. If a n 1 is prime, then a is 2 and n is prime. Usually the first step in factoring numbers of the forms a n 1 (where a and n are positive integers) is to factor the polynomial x n 1.

Induction Proof that 2^n > n^2 for n>=5 | Physics Forums
Nov 15, 2011· Then you assume your induction hypothesis, which in this case is 2 n >= n 2. After that you want to prove that it is true for n + 1, that 2 n+1 >= (n+1) 2 . You will use the induction hypothesis in the proof (the assumption that 2 n >= n 2 ).

A beginner's guide to Big O notation Rob Bell
BigO notation just describes asymptotic bounds, so it is correct to say something like, for example, "Quicksort is in O(n!)," even though Quicksort's actual worstcase running time will never exceed O(n^2).
