Essential concepts and terminology to understand this topic
A theorem that provides a formula to expand powers of binomials as a sum of terms involving coefficients and variables.
The numerical factors in the expansion of a binomial, represented as C(n, k) or n choose k.
A triangular array of numbers where each number is the sum of the two numbers directly above it, used to find binomial coefficients.
A branch of mathematics dealing with counting, combinations, and permutations.
The mathematical operation of raising a number or expression to a power.
The process of breaking a binomial raised to a power into individual terms using the binomial theorem.
A binomial expression raised to an integer exponent, such as (a + b)^n.
The k-th term in the expansion of a binomial, given by T(k+1) = C(n, k) * a^(n-k) * b^k.
A formula used to calculate the number of ways to choose k items from n items, given by C(n, k) = n! / [k! * (n-k)!].
The product of all positive integers up to a given number, denoted as n!.
In binomial expansions, C(n, k) is equal to C(n, n-k), demonstrating the symmetry of coefficients.
The term(s) at the center of a binomial expansion, particularly when n is even or odd.
Real-world and mathematical uses of the binomial theorem, such as probability and series approximation.
A pattern where the exponents of one variable increase while the other's decrease in each term of the expansion.
Using the binomial theorem to approximate values in cases like (1 + x)^n for small x.
