Summary – Pascal’s Triangle
Pascal’s Triangle is a triangular arrangement of numbers where each number is the sum of the two numbers directly above it. Named after the mathematician Blaise Pascal, this triangle starts with a single 1 at the top, and each row begins and ends with 1. The numbers in Pascal’s Triangle correspond to the coefficients in the binomial expansion, making it useful in algebra, probability, and combinatorics. Patterns within the triangle include sums of rows being powers of 2, connections to the Fibonacci sequence, and the presence of prime numbers. Pascal’s Triangle is also helpful in calculating combinations and understanding outcomes in probability experiments, like coin tosses.
Pascal’s Triangle
Pascal’s Triangle is a numerical pattern arranged in a triangular form. This triangle provides the coefficients for the expansion of any binomial expression, with numbers organized in a way that they form a triangular shape. i.e. the second row in Pascal’s triangle represents the coefficients in (x+y)2 and so on.
In Pascal’s triangle, each number is the sum of the above two numbers. Pascal’s triangle has various applications in probability theory, combinatorics, algebra, and various other branches of mathematics.
