STEP II does not rely on any Further Maths, so all questions are possible without going Further (And it's arctan - aka tan^(-1) - that works for this.)
Comes in handy though. Also, for mechanics+Stats you're occasionally going to need M3+/S3+ which only people who do further maths will have done.
This thread has slowed down quite a lot...time for a question Prove that the sum of the product of 4 consecutive odd or 4 consecutive even integers and the number 16 yields a square.
EDIT: If you know double factorials then it is show (n+8)!!/n!! +16=k^2

The double factorial is one of my least favourite pieces of notation... I would recommend avoiding it if at all possible in the future, there's nothing that can be written as a double factorial that can't be written in a way that is cleaner and almost as concise!

Any particular reason why you hate it so much? I never really use it but I thought the question was slightly unclear without it.
