What is the Binomial Theorem?

Back

The Binomial Theorem provides a formula for expanding expressions of the form (a + b)^n, where n is a non-negative integer. It states that (a + b)^n = Σ (n choose k) * a^(n-k) * b^k for k = 0 to n.

What is Pascal's Triangle?

Back

Pascal's Triangle is a triangular array of the binomial coefficients. Each number is the sum of the two directly above it, and it is used to find coefficients in the expansion of binomials.

What is the formula for the binomial coefficient, often denoted as 'n choose k'?

Back

The binomial coefficient is given by the formula C(n, k) = n! / (k!(n-k)!), where n! is the factorial of n.
