    ATAR estimate

    Hey everyone, A friend has recently asked me for an ATAR estimate. I'm not too sure if I'd be correct because things may have changed since the UAI, but here are his trial marks and overall ranks for each subject. School rank about 60th. English: 61% - 50/136 (Trial rank 70/136) Maths Ext 1...

    Uni maths

    Thanks all for your advice. Our teacher taught us this. Isn't it when you get a limit where the result is mathematically indeterminable, you can differentiate the numerator and denominator in terms of the variable of the limit and it works out? (eg. lim x-->0 sinx/x)

    Uni maths

    Thanks... How disadvantaged would one be if they didn't do 4U maths? I'm asking cos I may be teaching a friend elements of 4U maths for Engineering before uni starts. He only did 3U. So you reckon I should just disregard Conics, volumes and harder 3U? Cheers

    Uni maths

    Hello everyone, I've heard that in the 1st or so week of uni for Engineering you do 4U maths. Which topics would there be an overall focus on? Cheers

    What is the most interesting HSC science course

    You have to be kidding right? Most people do Physics (or Chem) for the actual science involved. If they liked history, then they'd do something like Ancient History or something.

    What is the most interesting HSC science course

    You said it --> History of Science. Most people who have an interest in science, are interested in the real science, not some history of how theories were formed etc. Studying sciences at USyd is a totally different story too.

    Dear CityRail

    Then you should've waited for an a/c'ed train.

    Was that a Maths exam?

    Do yourself a favour and stop digging yourself in a bigger hole. Do I really need to spell it out? Basic argument was that in HSC it doesn't matter if your answer is off by a few decimals or so, aslong as you show all working. Then others took marking guidelines out of context as the marking...

    simple complex number

    z^2+2z(1+2i)-(11+2i)=0 \\ z= \frac{-2(1+2i) \pm \sqrt{4(1+2i)^2-4.1.-(11+2i)}}{2} \\ z=\frac{(-2-4i) \pm \sqrt{4(1+4i-4) +44+8i}}{2} \\z=\frac{-2-4i \pm \sqrt{12+16i + 44 + 8i }}{2} \\z=\frac{ -2 - 4i \pm \sqrt{56+24i}}{2} \\ Now \ let \ \sqrt{56+24i} = u+iv \ (where \ u, \ v, \ \epsilon \...

    Was that a Maths exam?

    I find it funny how you need to refer to other past threads in other to justify your humiliation in this thread. And how was I burned in that thread? Non uniform circular motion (in the sense of deriving tangential and normal components) is indeed examinable in the current Extension 2...

    PHYSICS Tutoring @ $20/hr - Eastwood/Strathfield/Hornsby area

    You don't need to use a calculator in HSC Physics. I thought we established that in the other thread. There will be more coming ;)

    PHYSICS Tutoring @ $20/hr - Eastwood/Strathfield/Hornsby area

    A bit contradictory isn't it? So, bottom line = You will not help any Year 11 student with their assessments and tests. You do realise that some people will want tutoring with Year 11 work right? But also, the basis of the HSC course is the preliminary course. Take for instance the multiple...

    What would you like the preliminary and HSC physics courses to be like?

    Point is, in "pure Physics", or any physics for the matter, they do not use 100% maths. There are concepts involved and as the others said, maths is just a tool. What do astronomers do anyway? "Oh hey, look at that star OMFG!!! It just exploded!!!" or "Oh no, red shift, the universe is...

    Teaching Extension 1

    There this really good math teacher at our school who is both popular and is an extremely good teacher. Some points you may want to note about this teacher, - He covers the math syllabus extensively and gives hard examples. ie. He has his own massive book of notes covering every aspect of the...

    What would you like the preliminary and HSC physics courses to be like?

    That's what the old Physics course used to be like. It was very numerical and you'd get the odd question like "Explain what happens when a magnet is dropped down a copper tube" etc.. That being said, the "maths" in Physics at the moment isn't really maths in my opinion. I mean come on, you're...

    Is it worth doing Adv. english if it only ups your uai by 0.4?

    How many mathematicians does it take to screw in a light bulb? (Use a calculator if you're not sure ;) ) Now getting back on topic... I read on here somewhere a year ago or so that Standard English is scaled slightly less than Advanced English.

    Is it worth doing Adv. english if it only ups your uai by 0.4?

    No, someone's told me that Standard English scales slightly less than Advanced English. But of course that isn't the reason that it's difficult to attain a band 6 in the subject.
