2012 Sec 4 Integrated Mathematics

Term 1 : Unit 3

Unit 3 : Binomial Theorem


1. construct the Pascal’s triangle (via tossing coins) and use it to expand (a + b)^n, especially for smaller values of n.

2. use the Binomial Theorem to expand (a + b)^n for positive integer n.

3. use of the general term Tr + 1 to find a particular term in the expansion of (a + b)^n.

4. know the notation n! and nCr .
