This two part series covers the binomial theorem and binomial coefficients. To start with, Professor Burger reviews binomials. Then, you will learn what the Binomial Theorem is and how and when to apply this formula; used for writing out the powers of a binomial without manually multiplying it out. Additionally, you will learn what the relationship is between the Binomial Theorem and Pascal's triangle and how and when to use Pascal's triangle. To cement this knowledge, you will then work through an example problem by expanding (x+y)^4.

The second lesson in the series answers the question, "How do you find the binomial coefficients appearing in the binomial theorem?" To do so, you'll use the factorial function (denoted as n! and called n-factorial). After walking through this information, you'll learn how to use the binomial coefficient (or binomial theorem). Thus, you'll learn to evaluate 'binomial coefficient n m' or 'n choose m.' Professor Burger also describes the relationship between the binomial coefficients and Pascal's triangle and walks you through an example of how to apply the binomial theorem. He solves (2A-B)^5 using both Pascal's triangle and binomial coefficients to arrive at 32A^5 - 80A^4B + 80A^3B^2 - 40A^2B^3 + 10AB^4 - B^5.

This series is perfect for review for a CLEP test, mid-term, final, summer school, or personal growth!

Lol, the number one sound clip was worth the two bucks.

Anyways, good clip, doesn't waste time and doesn't go too fast.
