the quality is decent when i press on it, does it not work for you? I dont reallt know how to upload otherwise
For limits questions, do people use "+..." or "+O(x)" ? Not sure which one i should use or if i should state what O(x) means.

can you give an example?

I normally put O(x^n) where n is whatever the degree of next term in sequence is.

I use o(x)
I've seen it in mark scheme and also TeeEm's workbook. Tbh even if the examiner doesn't know the notation it should be quite obvious

Yeah I do this too (having seen it used in the mark schemes all the time). Although for people using 'O', that's wrong. It should be a little 'o': it's officially called 'little o notation' and there is in fact another thing called 'big o notation'.

Written solutions Swag master?
Just to clarify the above.

Big O (f(x)=O(g(x))f(x) = O(g(x)) is: for at least one choice of a constant k>0k > 0, there exists some constant aa such that the inequality f(x)≤kg(x)f(x) \leq k g(x) holds for all x≥ax \geq a.

Small o (f(x)=o(g(x)f(x) = o(g(x)) is: for every choice of a constant k>0k>0, you can find a constant aa such that the inequality f(x)≤kg(x)f(x) \leq kg(x) for all x≥ax \geq a.

Note that both O and o are sets and that the above should be written with absolute values in the relevant inequalities but it looks ugly, so I'm leaving them out.

I think he meant it as a joke the second time

Hey, where's that worksheet? :biggrin:

But we can use '+...' right?
Has Euler's identity been used in a paper yet? What sort of question could we expect it appear in?

I've only seen it being mentioned in the FP3 textbook but never any actual questions on it in papers.

Haha thanks I will make sure my o's are small.

The way it's mentioned in the spec sounds as thought we only need to know what h k1 etc all mean and be able to use the formulae

Alright, cool. I was worried it would end up being a suprise question 7 that everyone ends up flopping. Right in between the 14 mark polar co-ordinate question 6 and the 16 mark polar co-ordinate question 8.
Could anyone explain Q8bii? Tried sine rule but I think it's the ambiguous case which then confuses things

There are several ways (I think like 4) to do this question but i think using sine rule is the easiest
