    post trials estimate please :)

    It'd be more useful if you gave us the exact ranking of your school last year so we can have a look at the performance trend over the years. But based off what you gave us, and assuming last year's performance is a good reflection of your school's general performance, I would agree with the...

    Thoughts on Independent 2014 MX2 Trials?

    Re: thoughts on independent 4u 2014? Were there any hard questions in the paper?

    Prelim 2016 Maths Help Thread

    lmao why does eyeseeyou keep asking people how to state rank in maths lol. Judging by his abilities, shouldn't he be asking how to get at least a band 3?

    Hard Circle geometry question

    Sounds different to what i was expecting, but it seems like legit progress so can you upload your solution? But what did you mean by T?

    Hard Circle geometry question

    Ah, sorry about that, that was my mistake. All euclidean geometry is welcome and fine. No vectors though

    Hard Circle geometry question

    Yeah dw, im also used to people who cant solve a problem and try to cover it up by making a load of excuses such as claiming to merely be "leaving a hole" when they are actually stuck but need to maintain their ego. Dont feel too bad about not being able to do it though, even some ruse and...

    Hard Circle geometry question

    Lol, you lack understanding. The whole point of my last post wasnt because i specifically wanted a hsc proof for this question, i merely suggested that you present your "solution" in a clear and logical manner (presenting a solution using hsc tools was just one way i suggested in order to...

    Hard Circle geometry question

    Lol, even now you still make claims without any proof (you are still yet to prove your claim), instead of just making vague references to spiral similarity To make yourself clear, I suggest you prove your claims via using hsc tools

    Hard Circle geometry question

    I've interpreted your claim as: "Suppose we have two similar quadrilaterals, ABCD and EFGH. Call the midpoint of AE as X, and CG as Y. Also, label the midpoint of CD as P and FH as Q. Then, XYPQ is similar to both these quadrilaterals." If this is what you mean, there are counterexamples to this...

    Spiral similarity isn't a theorem

    Hard Circle geometry question

    As expected, on that page there is nothing to support your claim that if "Each of the corresponding vertices are the midpoints of the exterior vertices" then the figures are similar If you disagree, provide your full solution

    Hard Circle geometry question

    What do you interpret spiral similarity as?

    Hard Circle geometry question

    Yeah, there's a few steps which I thought were very difficult to see, so I'm trying to see whether other people could see (I personally could not crack this problem by myself, had to peek at the solutions)

    Hard Circle geometry question

    Also please explain the part "Since the vertices of the inside quadrilateral are all exactly halfway between the corresponding vertices (p=0.5), the quadrilateral formed is similar to the two corresponding quadrilaterals." This has no clear justification behind it

    Hard Circle geometry question

    Yes please do have a look again tomorrow. I believe that this problem will remain unsolved for quite some time though, (The solution is actually very tricky)
