Binomial formula induction
WebMar 27, 2015 · The expansion of (A + B)n for non-commuting A and B is the sum of 2n different terms. Each term has the form X1X2... Xn, where Xi = A or Xi = B, for all the different possible cases (there are 2^n possible cases). For example: (A + B)3 = AAA + AAB + ABA + ABB + BAA + BAB + BBA + BBB. You can understand how these terms are … WebTo prove this formula, let's use induction with this statement : $$\forall n \in \mathbb{N} \qquad H_n : (a+b)^n = \sum_{k=0}^{n} \binom{n}{k} a^{n-k} b^k$$ ...

In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial. According to the theorem, it is possible to expand the polynomial (x + y) into a sum involving terms of the form ax y , where the exponents b and c are nonnegative integers with b + c = n, … See more Special cases of the binomial theorem were known since at least the 4th century BC when Greek mathematician Euclid mentioned the special case of the binomial theorem for exponent 2. There is evidence that the binomial … See more Here are the first few cases of the binomial theorem: • the exponents of x in the terms are n, n − 1, ..., 2, 1, 0 (the last term implicitly contains x = 1); • the exponents of y in the terms are 0, 1, 2, ..., n − 1, n (the first term implicitly contains y … See more Newton's generalized binomial theorem Around 1665, Isaac Newton generalized the binomial theorem to allow real exponents other than nonnegative integers. (The same generalization also applies to complex exponents.) In this generalization, the finite sum is … See more • The binomial theorem is mentioned in the Major-General's Song in the comic opera The Pirates of Penzance. • Professor Moriarty is described by Sherlock Holmes as having written a treatise on the binomial theorem. See more The coefficients that appear in the binomial expansion are called binomial coefficients. These are usually written $${\displaystyle {\tbinom {n}{k}},}$$ and pronounced "n choose k". Formulas The coefficient of x … See more The binomial theorem is valid more generally for two elements x and y in a ring, or even a semiring, provided that xy = yx. For example, it holds for two n × n matrices, provided that those matrices commute; this is useful in computing powers of a matrix.

WebJul 12, 2024 · Since we have counted the same problem in two different ways and obtained different formulas, Theorem 4.2.1 tells us that the two formulas must be equal; that is, ∑ r = 0 n ( n r) = 2 n. as desired. We can also produce an interesting combinatorial identity from a generalisation of the problem studied in Example 4.1.2. WebFor this reason the numbers (n k) are usually referred to as the binomial coefficients . Theorem 1.3.1 (Binomial Theorem) (x + y)n = (n 0)xn + (n 1)xn − 1y + (n 2)xn − 2y2 + ⋯ + (n n)yn = n ∑ i = 0(n i)xn − iyi. Proof. We prove this by induction on n. It is easy to check the first few, say for n = 0, 1, 2, which form the base case.
