thanks for the replies. the decision really should depend on which one is more enjoyable. Sportsgal - is SOR1 not difficult even for someone who is not catholic?

This is probably aimed more at year 12s, but open for anyone to add comments :) If you had to choose between Biology and Chemistry, which would you drop and why? I know that the choice should be a personal one, i.e. person dependent, but i'm looking for other people's opinions having been...

Not really along the same lines, but almost: the (regular) absolute value of a number is the distance from the origin. You can define, on the rationals, other types of absolute values (though it is always a non-negative number) based on its prime factorisation (prime factorisation of the...

not sure about a general formula for the original problem... for the 52 cards one, is it 52^5?

This thread reminds me of the integral of sec(x) dx.

need to put functions into integrator correctly. Press the button "How to enter your input". logarithms base e are Log[x]

you shouldn't always believe what you are told in high school. There is so much stuff left out in high school, but at the same time, it's impossible to cover everything in high school. I suppose you wouldn't ever be given a question like that at the high school level...

we are working in a field, so if a is not zero, then it has an inverse, call it c. then ac = ca = 1 since ab = 0, then 0 = c.0 = c.ab = b so b = 0.

I'm not sure about what subject santaslayer is talking about. MATH1001 does not give assignments back during tutorials. Nor does MATH1002.

Thank you for that Martin! I had that paper in my hands a few years ago, but I didn't even get past the first page. Only when I reread the first bit (of your post) that I remembered that Liouville had something to do with it. Your post will make a lot more sense if I read it with pen and...

I'm inclined to think that some subjects do that. Yeah...i remember my chem lab quiz results were posted up on notice boards. That was the only way to find out how you went. or maybe they were the chem assignments. I dont' remember. But they never post up marks against your name, only...

For Math, the assignments would be returned via the boxes on the third floor of Carslaw, close by to the assignment collection boxes. As of now (Sunday) they have not been placed there yet. It is also your own initiative to go and collect them. Otherwise, at the end of semester, the...

Who are your lecturers and who are your tutors? What do you think of them? Does the tutor help you in anyway? I'm just wondering because the tutors don't formally get any feedback from the students. This is for MATH1001, but comments on other math courses/lecturers/tutors are welcome.

that's generally the way to go... i would call it "angle chasing"....bashing is for cases, i.e. case bashing

you are right...what was i thinking? what did i drink last night? yes...john nash. (who is martin nash? beats me...) Edit: Martin Nash is a card magician, and a very skilled one at that. Forgive me for getting the names mixed up...

You are right, it's not hard to derive them at all. You just need to be able to integrate properly. Most the time, you get simple things to integrate. Then comes mechanics, which is like projectile motion in harder terms, and tougher conditions/considerations. Here, you might get some nasty...

projectile motion in physics is different from projectile motion in mathematics. You need to 'derive' the equations of motion in mathematics for each question, rather than state the equations like you do for physics (which are given to you on a formula sheet).

Oh, and I forgot to mention Martin Nash, the mathematician in A Beautiful Mind. The movie does not do justice to the book.

Grothendieck is a mystery to most people. But more is being done to try and understand him and his ideas. He started out in Topological Vector spaces, but later became a leader in Algebraic Geometry. More can be found at http://www.grothendieck-circle.org/ and...

Li(x) is Logarithmic integral. It is basically the integral of dt/(ln t) from 0 to x. http://mathworld.wolfram.com/LogarithmicIntegral.html Strongly related to the Prime Number Theorem. This makes things interesting because Primes are discrete things, like Algebra. 2,3,5,7,11,13...
