    You've seen this before... If you're a newcomer! This is the 3rd A-level Maths thread!

    This is for discussion for all boards from C1-4 M1-3 S1-3 and FP1-3

    As these are the modules available to all!

    But of course you can also.discuss:
    D1-2 FP4 M4-5 S4

    Post questions, help, tips and messages

    Good luck!

    Edexcel Maths A-level dependency table
    http://www.thestudentroom.co.uk/atta...hmentid=237097
    Notes:
    - The arrows show dependency one way. The arrow pointing from C1 to C2 shows that C2 is dependent on C1.
    - If A is dependent on B, and B is dependent on C, then A is dependent on C. For example, C3 requires C2 and C2 requires C1 so C3 requires C1.
    - If a module has no arrows before it (C1, S1, D1) then it is not dependent on any previous A level knowledge.
    - This table is for Edexcel only. Don't ask for one for other exam boards; I haven't done them and so don't know the dependency and if I made one it would be wrong.

    Thanks DJ Mayes for these very useful tables!

    We're all friends here that just enjoy doing Maths, does it really matter who creates the thread? Just as long as we can all benefit from each other then we should all be fine

    Come on boys, let's wrap this thread up!

    Let \alpha , \ \beta , \ \gamma be the angles of a triangle. Show that \tan \alpha + \tan \beta + \tan \gamma = \tan \alpha \tan \beta \tan \gamma

    Go go go :gah:
    A bit of an underwhelming last question, is it not? :smug:

    The other thread closed before I was done texing my solution :facepalm:

    \alpha + \beta = \pi - \gamma

    \tan (\alpha + \beta) = \tan (\pi - \gamma)

    \dfrac{\tan \alpha + \tan \beta}{1 - \tan \alpha \tan \beta} = -\tan \gamma

    \tan \alpha + \tan \beta = -\tan \gamma (1 - \tan \alpha \tan \beta)

    \tan \alpha + \tan \beta = -\tan \gamma + \tan \alpha \tan \beta \tan \gamma

    \tan \alpha + \tan \beta + \tan \gamma =  \tan \alpha \tan \beta \tan \gamma

    I think a maths duel would be more appropriate but knowing Usy I'll still have the thread, all in good will fish, I'm passing on the legacy of the year 12 (soon 13 thread) onto Justin as intended initially

    I know I know but I was just trying to think of something and was trying to get the 10 000th post :teehee: (damn you Aurorae )

    I was wondering what you were going on about on the other thread! And guys...off topic so early :P.

    Anyone got any maths questions that I can look at between black ops breaks?

    I'm sure I've seen some random language ones around that you've made and some others somewhere too
