    Further Mathematics: Post your doubts here!

    Thanks for that. So if I'm not mistaken you are using the general formula aS[k] +bS[k-1] + cS[k-2] + dS[k-3] = 0 ? Do you know the general formula for quartic equation?

    Further Mathematics: Post your doubts here!

    Too slow guys...I found this: http://mathforum.org/library/drmath/view/70508.html Now can anyone derive a general formula for the sum of roots to the nth power for quartic equations? I'm working through this as we speak but I am not known for quick calculation.

    How to take Further Maths?

    Where can I find the notes? They don't have to be too detailed but not too general like the syllabus. I just want to make sure I covered the syllabus completely. I can't find any textbook from CIE & the Oxford one is a little bit unorganized.

    How to take Further Maths?

    I'm planning to take Further Maths. I'll be learning the subject by my own. So can anyone guide me? Is it the same with Maths, whereby we are required to choose units from P1/S1/P3/M1? How will the exam papers be?

    Physics: Post your doubts here!

    Physics M/J paper_12 2013 Yes I agree too, I'm just curious about the 'increase with increasing rate' near the origin region. I think it's because at that region air resistance isn't so significant yet. Since a=(v^2)/2s & F=ma, whereby aceleration is constant (gravity)...shape of graph should...

    How was the AS chemistry practical 31 ?

    What kind of questions came out in the paper for "analysis, conclusions and evaluation"? Example: Suggest a method to reduce error, outline an alternative method to find volume etc.

    AS Physics (9702) Paper 22 Answers and Discussion

    That's very detailed of you! Couldn't have come up with that. But acceleration 0 implies force 0, that would contradict the force/time graph despite the statement of initially at rest. CIE is also testing your sensitivity, besides cleverness. The sample of answers given above have so many loose...
