For example, the sum of the first 50 natural numbers is, 50 (50 + 1) / 2 = 1275. What Are the Applications of the Summation Formulas? The summation formulas are used to find the sum of any specific sequence without actually finding the sum manually. For example, the summation formula ...
Geometric Progression sum formula (Sn) = a1 (rn -1)/ r-1 for r ≠ 1 Sum of Infinite Series Formula Sum of an infinite series formula for the geometric formula with the common ratio r satisfying |r| < 1 is given as: S∞ = \[\frac {a}{1-r}\] The notation for the above sum...

We also derive multidimensional extensions, associated to the classical root systems of type Ar, Br, Cr, and Dr, respectively, of Chu's bilateral transformation formula for basic hypergeometric series of Gasper–Karlsson–Minton type. Limiting cases of our various series identities include ...
Euler-Maclaurin summation formulaasymptotic formulaeLet $n$ be a fixed positive integer. In this article we obtain asymptotic formulae for $sum^{N}_{j=1} j^n log j$ and $prod^{N}_{i=1}j^{(j^n)}$. For example if $n=1$ we obtain the asymptotic formulae,[sum^{N}_{i=1} ...
Note that for the fluid part of (1.23), information propagates at the sound (and shock) speeds, but the gravitational potential ϕ is updated “instantaneously”, depending only on the density ρ(x, t), according to the formula (1.21). In contrast, for Einstein's theory of gravity, ...
