WebThe multinomial theorem describes how to expand the power of a sum of more than two terms. It is a generalization of the binomial theorem to polynomials with any number of terms. It expresses a power $ (x_1 + x_2 + \cdots + x_k)^n $ as a weighted sum of monomials of the form $ x_1^{b_1} x_2^{b_2} \cdots x_k^{b_k}, $ where the weights are … WebThe Gaussian binomial coefficient, written as or , is a polynomial in q with integer coefficients, whose value when q is set to a prime power counts the number of … imperial dock services bridgton maine

WebJun 25, 2024 · To get all the permutations of X we repeat the procedure with Y replaced by each of the k-order subsets. Thus the total possible permutations would be T.k! (n-k)! where T is the number of k-order subsets. That is because total permutations = adding k! (n-k)! the number of times equal to the number of k-order subsets = T.k! (n-k)!. WebJul 28, 2016 · Let $\dbinom n k$ be a binomial coefficient. Then $\dbinom n k$ is an integer. Proof 1. If it is not the case that $0 \le k \le n$, then the result holds trivially. So let $0 \le k \le n$.

"In mathematics, the binomial coefficients are the positive integers that occur as coefficients in the binomial theorem. Commonly, a binomial coefficient is indexed by a pair of integers n ≥ k ≥ 0 and is written $${\displaystyle {\tbinom {n}{k}}.}$$ It is the coefficient of the x term in the polynomial expansion of the … See more Andreas von Ettingshausen introduced the notation $${\displaystyle {\tbinom {n}{k}}}$$ in 1826, although the numbers were known centuries earlier (see Pascal's triangle). In about 1150, the Indian mathematician See more Several methods exist to compute the value of $${\displaystyle {\tbinom {n}{k}}}$$ without actually expanding a binomial power or counting k-combinations. Recursive formula One method uses the recursive, purely additive formula See more Binomial coefficients are of importance in combinatorics, because they provide ready formulas for certain frequent counting problems: • There … See more The factorial formula facilitates relating nearby binomial coefficients. For instance, if k is a positive integer and n is arbitrary, then See more For natural numbers (taken to include 0) n and k, the binomial coefficient $${\displaystyle {\tbinom {n}{k}}}$$ can be defined as the coefficient of the monomial X in the expansion of … See more Pascal's rule is the important recurrence relation $${\displaystyle {n \choose k}+{n \choose k+1}={n+1 \choose k+1},}$$ (3) which can be used to prove by mathematical induction that $${\displaystyle {\tbinom {n}{k}}}$$ is … See more For any nonnegative integer k, the expression $${\textstyle {\binom {t}{k}}}$$ can be simplified and defined as a polynomial divided by k!: this presents a polynomial in t with rational coefficients.
