    I never understood how people manage to do this but people have done it in the past... just out of curiosity why are you trying to learn it in 7 days, and not since september? :dontknow:

    Depends on what you mean by "basic knowledge"

    If you have a full understanding of the C1 and C2 material and no other exams to study for, then sure

    Whilst were talking about maths Can someone whose good at maths quickly verify this for me (been trying to use the internet but all sorts of scary things are appearing). If you differentiate tan x do you get sex^2x and is it true that sec^2x is the same as 1/cosec x? (quote me please)

    @ Bulbasaur, Have 7 Exams in January to study for, Let's just say I took a months rest from sept - oct. And from October, I did 2 units in 2 months. Now I have 1 month left to study 5 other units. And I only had 1 month. I've finished all units except 2 now and C3 Is one of them. And the only available time i'd have is 7 days. Is it possible?

    Yes, d/dx(tan(x)) = sec^2(x). No, sec^2(x) is not the same 1/cosec(x). It is the same as 1/cos^2(x)

    C3 has been a bit of a ***** for me in parts but then I've been working in a very unfocused manner. I have to get good at Chapter 7 and learn Chapter 8 before I can then begin teaching myself the C4 material. Then again I only need to pass the A-level for what I need it for, and I only need at get an E in one of C3/C4/S1 and fail the other two to do that.

    thats very important , trust me , im currently doing revision for maths too , doing the past papers is the best way to learn things quickly and fast, also as you do them you will start to see trends and patterns of the type of questions they ask you and you will be much more confident when you are doing the actual exam , so start doing them

    Can I just throw a question in here...?

    It's probably really simple, but if the domain of f(x) is x is all real values, how do you work out the range?
    It's for f(x) = e^2x + 3 (on Jan 2010 paper).

    We did this stuff at the end and my notes for then were a mess
    Cheers

    Think about the graph.

    "f(x)= e^x" is always above 0. So with graph transformations, +3 outside the bracket it an increase in the Y value by 3. Because of this the range is now f(x) > 3.

    EDIT: I don't think the domain is all real values. It should be x>3 also? X being the domain.

    Sec^2x = 1/cos^2x
    but 1 + cot^2x = sec^2x
