    2017 HSC Mathematics Extension 2 paper thoughts?

    I think 8) should be B F(x) = f(f(x)) F(-x)=f(f(-x)) =f(-f(x)) =-f(f(x)) =-F(x) therefore odd

    Why won't selective schools+top private schools have more subject accelerations

    It depends what you mean by "did not work" If the goal was increasing the number of Band 6's the school achieved, then you are correct. However, learning is not about how many Band 6's you get If the goal was, to allow Year 9/10 students to experience the senior level of work early, without...

    School Rankings 2014

    It really depends on a couple of factors; 1. how many support unit students are in the year, its not the same every year. 2. what sort of gap is between the scholls, will it make an effect e.g. in 2013 Baulko ranked 2nd, if you removed the LifeSkills, they would still be 2nd (i.e. not...

    School Rankings 2014

    I don't know why you say as "as expected". When looking at the Baulko stats something the data does not tell you. The 1343 total attempts includes 72 attempts from the students who did Life Skills courses. For those who don't know what LifeSkills courses are, they are for students with...

    Given up.. i guess

    You can still apply without the NAPLAN results. It just makes it a little bit hard for comparison unless there are others from your school. Put it this way, if you don't apply then you have zero chance of getting in. You have to remember that Baulko actually take in several people into Year 9...

    Trial Question

    If you happen to know the standard integral, then use it and save time. It is no different to just quoting log sec x for the integral of tanx. If they want you to use partial fractions, then they will state "integrate using partial fractions", if they don't then just write it down.

    Probability question

    Another way of thinking about it; 1. Place the father in the circle, as it is a circle there is no defined positions so there is only one way way of doing this, and this is to put him in the circle. (1 way) 2. Now place the mother, as someone is sitting in the circle positions can now be...

    Re: James ruse 2011 trial papers? The Catholic papers are also subject to copyright, I would assume those posts will also be deleted?

    2011 trial uploads!!!

    I have no problem with uploading school written trials e.g. Sydney Grammar, Ruse, Baulko etc, as they are not subject to copyright, and by uploading them you are not potentially depriving the authors of income. (that is, after all the point of copyright legislation) I do have a problem with...

    What a wonderful attitude.

    2011 trial uploads!!!

    Grow up. Have you ever heard of the saying that if you have to resort to abuse you have lost the argument? The copyright date is still valid, the release date is a security period so that people do not gain an advantage in trials. As for trying to justify only uploading 25%, the paper and the...

    2011 trial uploads!!!

    Again, not a good analogy, I reiterate my points; 1. not a life and death situation 2. legal alternative is readily available Can you come up with a situation where it is OK to break the law under these conditions?

    2011 trial uploads!!!

    Your analogy is poor; 1st: it is hardly a life and death situation 2nd: there is a legal alternative readily available Try using a fair analogy to claim it is ethical

    Resolve your forces horzontally and vertically; Tension will have a vertical component of 50sin30 and a horizontal component of 50cos30 Normal force and mg are purely vertical forces vertical F: my''= N - mg + 50 sin30 but the forces are balanced vertically i.e. my'' = 0 0 = N - mg + 50...

    Official Board of Studies workbooks

    Yes it is legal, you are submitting solutions to the BOS to their problems. Once you submit them they become the property of the BOS.

    So its OK to break the law if it helps others?

    2011 trial uploads!!!

    No need for forgiveness, good on you for respecting the intellectual property of others and not caving in to peer pressure. Its a very rare thing. Schools are allowed to photocopy the Catholic Trials, if they purchased them, for assessment purposes. Review for the HSC is an assessment purpose...

    Yes, demand acknowledgement that you have breached the copyright regulations that you cleverly scanned on page 12. How dare he devalue the one hour you spent scanning, pity about the many hours the authors took writing the paper!!!! By the way did you pay attention when doing "All my own work"?

    Teachers crossing the line

    Whilst I agree that your teacher was out of line, what about the ethics of not studying for the 2 units. If you have decided to not study for these two units, then drop them. Your lack of performance can have an affect on the group's scaling. So whose ethics are worse? The teacher ridiculing...
