Basic Facts about Binomial Coefficients
Basic Facts about Binomial Coefficients n ! There are many equivalent ways of defining (Read this as “n choose r ”) Here we r assume 0 ≤ r ≤ n 1 Here are four of doing this The Factorial Formula: n ! n! = r r!(n − r)! This is enough to give the basic identities n ! n ! n ! = = 1; = 0 n r 2 Recursion on r (Pascal’s triangle): ! − r 0 ! |

Notes on binomial coe cients
The binomial coe cient choose k\" written n (n)k n! = = ; k k! k! (n k)! counts the number of k-element subsets of an n-element set The name arises from the binomial theorem which says that 1 X (x + y)n = k=0 n xkyn k: k For integer n we can limit ourselves to letting k range from 0 to n |

Binomial Coefficients and Identities
Binomial Coefficients and Identities Terminology: The number r n is also called a binomial coefficient because they occur as coefficients in the expansion of powers of binomial expressions such as (a b)n Example: Expand (x+y)3 Theorem (The Binomial Theorem) Let x and y be variables and let n be a positive integer Then n j x y n C n j xn j y |

Binomial identities binomial coefficients and binomial
In mathematics the binomial theorem is an important formula giving the expansion of powers of sums Its simplest version reads n y)n X (x + = k=0 k n xkyn−k whenever n is any non-negative integer the numbers n n! = k k!(n − k)! are the binomial coefficients and n! denotes the factorial of n |

Lecture 4: Binomial and Multinomial Theorems
In this lecture we discuss the binomial theorem and further identities involving the binomial coe cients At the end we introduce multinomial coe cients and generalize the binomial theorem Binomial Theorem At this point we all know beforehand what we obtain when we unfold (x + y)2 and (x + y)3 |
What is a binomial theorem?
In mathematics, the binomial theorem is an important formula giving the expansion of powers of sums. Its simplest version reads n n! k k!(n − k)! are the binomial coefficients, and n! denotes the factorial of n.
How do you find a binomial identity?
Many identities involving binomial coefficients (called binomial identities) can be found using the binomial theorem (1). For example, putting x = 1 in (1), we get (−1)r n ! = 0 (n > 0). (Explain why we need n > 0 here.) n ! = n2n−1. Here are a few problems to work on.
What is N A binomial coefficient?
Because of the binomial theorem, the numbers n are also called binomial coefficients. Other r . All of these 4 definitions are equivalent. That is, if we used any one of these results as the definition of n , the other results would follow. Some results to ! ! ! − 1 ! ✪ r r! 50 ! For example, to compute 10 !
