    Community MX1 Paper

    Yes :) What topics have you guys not done in your schools? So far I know of polynomials, circle geometry, and permutations and combinations. This is a hurdle T_T Might aswell strip the content to nothing lol...

    What is the square root of 9?

    Yes that cleared a lot up :) Thank you! I don't know why I always find myself questioning these types of things :P

    Yeah I don't think you understood my whole dilemma...

    What is the square root of 9?

    I'm having trouble mapping out the difference between principal (positive) square roots and... square roots. E.g. The principal square root of 9 = 3, however -3,3 are square roots of 9. CONFUSING? I was messing around with equations in my head when i stumbled upon root (x^2) = +-x then i...

    Bump! If no progress (participant count) for a while I'll have to call it off :(

    Community MX1 Paper

    Will do :) There is a significant difference between someone who is rank 50 in the grade vs rank 1. By using two filters (school rank, position in cohort), it is then more effective to compare two individuals from different schools (e.g. rank 1 in cohort of ~300 ranking school matches rank 10...

    Community MX1 Paper

    I'd like to place extra weighting on areas that are critical in year 12 (e.g. calculus, trigonometry, coordinate geometry) but it is all in theory at the moment!! If you have any ideas please share :) Mmhm, but I'd imagine the core (main) topics would be covered by most schools, and so it...

    How to perfect Complex Numbers?

    Yes my point exactly; you will lose to accelerators if you choose to play their own game of experience. They are not necessarily intelligent. I don't know you interpreted my response but simply that to get 99.95 you have to... beat everyone. It sounded like you were asking for help outside the...

    Community MX1 Paper

    To conclude the preliminary year, how many are interested in an MX1 paper (created by me)? The idea is to differentiate people of different schools to establish a relative ranking in the state. This data (arranged in a spreadsheet) will allow for motivation, competition, and also a reality...

    One must conserve energy when it comes to pointless arguments as when year 12 'starts'.

    Help pls

    Hmm disagree with last line "Angle AEB = 50 - x" I was only able to get Angle AEB = 10+x which makes it still unsolvable
  17. HSC2014

    Help pls

    You must be using a different diagram SpiralFlex o_o "Angle DFC = Angle EFD = Angle AEF = 40 degrees (why?)" But Angle DFC = 50, Angle EFD = 130

    inequality induction

    Here's a more simplistic example: Good: 2 = 4-2 > 3-2 (use of assumption here) = 1 Bad: 2 = 4-2 > 3-2 (use of assumption here) > 1 We stop using the inequality sign since otherwise it would say that some line is greater than the previous which is not true if we are only...

    Wow... I looked up my first thread ever on BoS. http://community.boredofstudies.org/showthread.php?t=288619 Year 10!! I didn't know I was born back then, seemed so long ago o_O Let's just say I have undergone much change since then, though still with the desire to succeed.

    How to perfect Complex Numbers?

    A wise man once told me "a smart student does not need to do a thousand questions unlike a (dumb) student". I see your ATAR goal is 99.95; consider this: there are people who have finished the year 12 math course before even starting the year (international, accelerated) - what chance do you...
