Binomial Theorem and Pascal's Triangle

Study Notes

A triangular array of binomial coefficients, where each number is the number of combinations of a certain size that can be selected from a set of items.
Each row represents the coefficients of the binomial expansion of (a+b)^n, where n is the row number.
Each entry is the sum of the two entries directly above it, except for the first and last entries in each row, which are always 1.

The binomial coefficients are the coefficients of the terms in the binomial expansion of (a+b)^n.
The k-th coefficient of the expansion of (a+b)^n is given by C(n, k) = n! / (k!(n-k)!), where C(n, k) is the number of combinations of k items from a set of n items.
The coefficients can be found using Pascal's Triangle.

Algebraic expansions: The binomial theorem provides a formula for the expansion of (a+b)^n, which is useful in algebraic manipulations.
Probability: The binomial coefficients are used in probability theory to calculate the number of combinations of outcomes in a binomial experiment.
Combinatorics: The binomial theorem has applications in counting and combinatorics, particularly in the study of permutations and combinations.
Calculus: The binomial theorem is used in the study of power series and Taylor series expansions.
