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 .


Starter :

a) When binomial expressions are expanded, is there any type of pattern developing which might help us expand more quickly? Consider the following expansions:


What observations can you make ?

Check in your findings here! You must identify yourself at the end of the reply.

b) Reading on Pascal Triangle : Using Ms Excel

Watch this video. http://www.youtube.com/watch?v=LUsczE6HkuM

You should try creating a pascal triangle on your own. Have you succeed?
