Expand and simplify ...

a + b

Find a pattern, add two more rows to the triangle ...

11 1

1 2 11 3 3 1

1 4 6 4 1

Evaluate each term ...n rC = n!

(n-r)!r!

Pascal's TriangleHow many different patterns can you find in the triangle?

The Binomial Theorem ...Algebraically

Combinatorically

Notice the patterns ...(1) The coefficient of the term is: (2) The exponent on a is given by: [n - (i - 1)](3) The exponent on b is given by: i - 1(4) This relation holds for each term in the expansion: [exponent on a] + [exponent on b] = n(5) The number of terms in any binomial expansion is: n + 1

Tomorrow we'll have a workshop class and we'll talk a little bit about poker. Wednesday will be a pre-test, and the test will be on Thursday.
