    Working with three variables

    Yes, but how is Q related to A, B and C? For instance, is Q=A*B*C? Q=A+B+C? Q =A^2+B^2+C^2, etc?

    Working with three variables

    And exactly how is Q determined?

    Japanese Language Proficiency Test Study Group (Levels 1-4)?

    Well, I don't think is is more study than learning maths. Different type of work, though. I would say that there is lots of memorisation involved, but that is it nowhere near as intellectually demanding as maths. Basically if you put the time in, you get the results. Can you read Chinese...

    Integration

    So your upper limit becomes infinity.

    Japanese Language Proficiency Test Study Group (Levels 1-4)?

    Oooh.. How exciting... ( にほんごのうろくしけん, I mean, not the salaryman stuff.) I sat the JLPT once. Decades ago. Which level are you attempting?

    What you hate about UNSW

    OK, I was wrong - that stupid library of ours does not have the book. However, you can get it on Amazon. Or just look at the pretty pictures so you know which book I am talking about. Amazon.com: A Guided Tour of Mathematical Methods: For the Physical Sciences: Roel Snieder: Books

    What you hate about UNSW

    When I was doing MATH2111, I found the Schaums' outline book Vector Calculus reasonably useful. (I generally find Schaums' outlines books are fairly crap, but if you get a good one it is wonderful because they are cheap.) You might be able to get it from the bookshop. Another fave of mine...

    failing 2u maths, should swap to general?

    If you are not willing to work harder, there is no point getting a tutor. You would just be wasting your time and money.

    Confusing log[sub]e[/sub],log[sub]10[/sub] & log

    Pender does maths like a mathematician, rather than a school teacher. So he uses "log" to mean the exponential logarithm, starts counting from zero,... etc. You'll also find that the topics he thinks shouldn't be in the syllabus (eg, probability) are shunted off to the end of the textbook and...

    Linear Algebra Questions

    Convert T into row-echelon form. Hence find the nullspace.

    Confusing log[sub]e[/sub],log[sub]10[/sub] & log

    Well, we don't hither or thither anymore, do we? Or use thee and thou.

    Advantages & Disadvantages of a Scholarship

    Problem: you don't actually get all the much cash in the hand with the DET scholarship - about $1500 a year, i think. The scholarship mostly consists of them paying your HECS debt for you. Which is one of the reasons I don't think it is a good scholarship - it does very little to improve your...

    Discrete maths 1081

    If you are a maths major you should do 1081. People complain about it because it is different from HSC maths, but it is actually not that hard.

    problem solving

    We solve this problem by reducing it to something more manageable. Let x=2a-b, y= 2b-c, z=2c-a. Then x+y+z= 2a-b+2b-c+2c-a = a+b+c = 0, by assumption. So we have to show that if x+y+z=0, then x^3+y^3+z^3-3xyz=0. But (x+y+z)^3 = x^3+y^3+z^3 +3(x^2y+y^2x+y^2z+z^2y+z^2x+x^2z) +6xyz...

    how to meet more people?

    When I was in first year, the main place that I made new friends was in physics tutorials and labs. Labs in particular were good because you have to work together to get the experiments done. Bio or chem would also be good for the same reason. Maths tutes on the other hand were just about...

    Studying maths ext.2 after high school

    MANSW is the subject association for maths teachers in NSW. The courses on that page are professional development courses for teachers who will be teaching MX1 and MX2 for the first time. Highly unlikely they will be of any use to someone who is trying to teach themselves MX2 content.

    Tired of Repetition

    What is it in particular that you are trying to memorise? There are various tricks and techniques to help you learn things better. Mostly they consist of trying to put the information into some sort of a meaningful framework which helps you remember it later.

    Morven Brown? The building that gives you cancer - best not to go there!!!

    Holiday courses

    The range of courses available is rather limited. They seem to be mostly first year courses in the sciences. There might be one or two arts courses that also run then. And there are always quite a few geneds. I did BABS1201 a few years ago (the first time that they ran it over summer...

    UAI numbers

    I think about 60000 student sit the HSC each year. Not all of them apply for a UAI, though. The UAI is calculated assuming that the whole year 10 cohort finishes the HSC, so they are still there in some phantom statistical sense.
