N(n-1)/2 formula

N(n-1)/2 formula- As @betlista has said, n (n1)/2 is the sum of the first (n1) numbers, that is 1 2 3 4 (n1) Now one might think that there is not much use for this formula, but when you do some research, you can find interesting uses for it @betlista has explained a few uses Here is a link which explains one usage I have to calculate n(n1)/2 for every (ai1ai1) where i is the index of the array and a is the generalized array Also consider corner cases from both ends They are to subtract 1 from first digit and then calculate n(n1)/2 and to subtract last digit from 11 and then calculate n(n1)/2 For eg

 Explanation Matrix A characteristic polynomial is p(λ) = 1 − 3λ 3λ2 −λ3 = −(λ −1)3 and A obeys this characteristic equation so A3 = 3 −3A I There is a difference equation associated to this relationship an3 = 3an2 − 3an1 an The difference equation solution is an = C0 nC1 n2C2 so finallyN,NDimethylethylamine's production and use as an intermediate in the manufacturing of quaternary ammonium compounds(1), in the production of mold cores(2), and as a stabilizer for chlorinated hydrocarbons and vinyl derivatives(1) may result in its release to the environment through various waste streams(SRC)95% Pricing Match Criteria Product Name

 U have written wrong formula of Sum Right formula is below Stepbystep explanation a ( n 1 ) d = term on n position Example 4 , 10 , 16 , 22 are in APThe 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 membersExponential Limit of (11/n)^n=e In this tutorial we shall discuss the very important formula of limits, lim x → ∞ ⁡ ( 1 1 x) x = e Let us consider the relation ( 1 1 x) x We shall prove this formula with the help of binomial series expansion We have

We have a sum of a series for " (n1)" number whose first number is "1" and the common difference is also "1" The Formula for Sum of a series is S = n 2a (n1)d/2 (where, n = total numbers, a = first number, d = common difference) So, it gives us the Total Communication ChannelN = 1/2 √ 961/4 Note that √ 961/4 can be written as √ 961 / √ 4 which is 31 / 2 Solve Quadratic Equation using the Quadratic Formula 53 Solving n 2 n240 = 0 by the Quadratic Formula According to the Quadratic Formula, n , the solution for An 2 BnC = 0 , where A, Number Sequences In the sequence 2, 4, 6, 8, 10 there is an obvious pattern Such sequences can be expressed in terms of the nth term of the sequence In this case, the nth term = 2n To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's 4th term = 2 × 4 = 8
