As a prototype, the SD40-2 was the most popular second-generation diesel with sales of over 3000 in the U.S. and more than 700 in Canada. There were many variations of this popular diesel because of the long production run, with Early units representing a pre-1990 appearance and Mid Production units depicting later runs of locomotives.

In mathematics, a power of two is a number of the form 2 n where n is an integer, i.e. the result of exponentiation with number two as the base and integer n as the exponent. In a context where only integers are considered, n is restricted to non-negative values, [1] so we have 1, 2, and 2 multiplied by itself a certain number of times.

Sum of n, n², or n³ ... The series \(\sum\limits_{k=1}^n k^a = 1^a + 2^a + 3^a + \cdots + n^a\) gives the sum of the \(a^\text{th}\) powers of the first \(n\) positive digits, where \(a\) and \(n\) are positive integers. Each of these series can be calculated through a closed-form formula.

The coefficients an and bn are called the Fourier coefficients of f and the series a0 2 + X∞ n=1 [an cosnx+bn sinnx] the Fourier series of f. We denote this fact by f(x) ∼ a0 2 + X∞ n=1 [an cosnx+bn sinnx]. The symbol ∼ should be read as f “has Fourier serier”.

In mathematics, the binary logarithm (log 2 n) is the power to which the number 2 must be raised to obtain the value n.That 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.

The major research on series of numbers like the Fermat numbers $ (2^{2^n} + 1) $ or the Mersenne numbers $ (2^n-1) $ 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.

In conclusion, we can say that the sequence (1) is convergent and its limit corresponds to the supremum of the set {a n} ⊂ [2, 3), denoted by e, that is:

Here we prove that if 2^n-1 is prime, then so is n. This is a key proof in understanding the Mersenne numbers.

Proofs by Induction A proof by induction is just like an ordinary proof in which every step must be justified. However it employs a neat trick which allows you to prove a statement about an arbitrary number n by first proving it is true when n is 1 and then assuming it is true for n=k and showing it is true for n…
