Pascal's Identity is a useful theorem of combinatorics dealing with combinations (also known as binomial coefficients). It can often be used to simplify complicated expressions involving binomial coefficients. Pascal's Identity is also known as Pascal's Rule, Pascal's Formula, and occasionally Pascal's Theorem. See more Pascal's Identity states that for any positive integers and . Here, is the binomial coefficient . This result can be interpreted … See more Pascal's identity was probably first derived by Blaise Pascal, a 17th century French mathematician, whom the theorem is named after. Pascal also did extensive other work on combinatorics, including work on Pascal's … See more Here, we prove this using committee forming. Consider picking one fixed object out of objects.

"WebObviously a binomial to the first power, the coefficients on a and b are just one and one. But when you square it, it would be a squared plus two ab plus b squared. If you take the third power, these are the coefficients-- third power. And to the fourth power, these are the coefficients. So let's write them down. " - Pascal's triangle combinations proof
