slide 6 - never mind, i see what you mean here - MAY BE infinite as it will be finite for n in Natural numbers

slide 6 - isn't it more correct to say that the expansion IS an infinite number of terms?

Slide 14, quickfire first step, fourth answer should have 1/125 rather than 1/25 as coefficient I think. Superb slides. Thank you.

Great site for students. If you do it in pdf form as well and if you add worksheets with solutions in every topics it will help a lot. Thanks.

Slide 5: The given formula at the top is something of a mishmash of the Y12 and Y13 version of the Binomial expansion. It suggests that the expansion is finite - because it has a last term and also that the nCr formula can be used when n is not a natural number - it can't.
