Wikipedia:Sum of radicals#0 | In mathematics, a sum of radicals is defined as a finite linear combination of nth roots: ∑ i = 1 n k i x i r i , {\displaystyle \sum _{i=1}^{n}k_{i}{\sqrt[{r_{i}}]{x_{i}}},} where n , r i {\displaystyle n,r_{i}} are natural numbers and k i , x i {\displaystyle k_{i},x_{i}} are real numbers. A particular special case a... |
Wikipedia:Sum of two cubes#0 | In mathematics, the sum of two cubes is a cubed number added to another cubed number. == Factorization == Every sum of cubes may be factored according to the identity a 3 + b 3 = ( a + b ) ( a 2 − a b + b 2 ) {\displaystyle a^{3}+b^{3}=(a+b)(a^{2}-ab+b^{2})} in elementary algebra. Binomial numbers generalize this facto... |
Wikipedia:Summability kernel#0 | In mathematics, a summability kernel is a family or sequence of periodic integrable functions satisfying a certain set of properties, listed below. Certain kernels, such as the Fejér kernel, are particularly useful in Fourier analysis. Summability kernels are related to approximation of the identity; definitions of an ... |
Wikipedia:Sumset#0 | In additive combinatorics, the sumset (also called the Minkowski sum) of two subsets A {\displaystyle A} and B {\displaystyle B} of an abelian group G {\displaystyle G} (written additively) is defined to be the set of all sums of an element from A {\displaystyle A} with an element from B {\displaystyle B} . That is, A ... |
