What is the Binomial Theorem?

Back

The Binomial Theorem describes the algebraic expansion of powers of a binomial. It states that (a + b)^n = Σ (n choose k) * a^(n-k) * b^k for k = 0 to n.

What is the formula for finding the coefficients in Pascal's Triangle?

Back

The coefficients in Pascal's Triangle can be found using the formula C(n, k) = n! / (k!(n-k)!), where n is the row number and k is the position in that row.
