    need help with math1141 calculus q's

    Q6 is easy to type up: i) f(x) -> f(a) as x -> a ii) 0 <= |f(x)| <= |x| When x = 0, 0 <= |f(0)| <= 0 Thus f(0) = 0 lim 0 <= lim |f(x)| <= lim |x| as x -> 0 0 <= lim |f(x)| <= 0 Thus f(x) -> 0 = f(0) as x -> 0 so f is continuous at 0 check me

    can max acceleration be negtaive

    For those of u saying that the maximum is "20 in the positive direction", r u guys saying that for vectors u = (u1, u2, ..., un) v = (v1, v2, ..., vn) max{u , v} is defined? What does it mean for one vector to be "greater" than another!?! I'd say the question's referring to...

    C++ Problems, please help!

    really? java does that to u? :p hehe.. i dont really like java compared to c.. meh anyway, about the problem - its just iteration! it cant b that hard Rach!! :p I guess this would work.. int userInput, n = 1, i; cin >> userInput; for (i = 0; i < userInput; ++i) { n = n...

    C++ Problems, please help!

    hehe! acmilan's program will never end if userInput >= 2. hahah :p sorry.. :p acmilan's logic will work if u replace the "n" in the 'for' condition with "userInput". EDIT: Um, no that won't work either

    C++ Problems, please help!

    Usually 'break' and 'continue' is used in place of properly formed if-then-else statements. Your teacher probably wants you guys to learn how to properly structure your programs using an if-then-else structure rather than 'jumping around'. You don't need to bother about what the progam does...

    CompSci vs SEng vs Comp Eng

    Oohh :( :( I know, I found out about the Comp Science specialisations the other day too, and there're lots of courses that I'd like to do but cant. :( Oohh :( I'm too far gone into my program tho. But I like it anyway. I like it I like it I like it.

    horizontal pt of inflexion

    I don't really understand your argument, but it's easy to disprove your "always" statement with this counter-example: y = -x^3 y' = -3x^2 y" = -6x y"' = -6 yet y = -x^3 has a horizontal point of inflexion. but i dunno if ive understood ur statement either! :)

    Task 1

    Anyway, you can 'cheat' by making haskell sort of iterative... f :: Int -> Int -> Int -> Int -> Int -> Int -> Int -> Int f reg1 reg2 reg3 reg4 reg5 reg6 reg7 = ... Hah, just do it like the cpu does

    Mathemagic help anyone?

    Or if you don't like drawing, 1. cos(x) = sqrt(square(cos(x))) = sqrt(1 - square(sin(x))) 2. sin(y) = ... (Use above technique) 3. sin(x-y) = sin(x)cos(-y) + cos(x)sin(-y) = sin(x)cos(y) - cos(x)sin(y) ... and use the given values and 1. and 2. 4. tan(y) = sin(y)/cos(y) 5...

    You can replace "cos" by "sin" above.

    Volume of Solids: Integration Question

    One way is to shift the y=sqrt(x) curve down by 5, so that you are revolving y=sqrt(x)-5 about the x-axis (which is y=0). The answer is then: pi * integrate[(sqrt(x)-5)^2]dx from 0 to 4.

    Have you been to a Careers workshop?

    Hey, have any of you guys been to a Careers workshop before? Or one of those Individual Assistance consultations? What do they do to you there? Is it just a very general talk on resumes and cover letters, like what you can read on the Careers website or books? And what about Individual...

    Uni Education - Makes you a better person?

    What does PL and QL stand for? Yeah, we also use the implies symbol ( ->, =>, <->, etc) and letters and stuff. I'm not suprised that this is studied in philosophy. One afternoon I was drifting through the philosophy section of the uni library and picked up a book on its history. Believe...

    Uni Education - Makes you a better person?

    You might learn about it in a Discrete Maths course (in UNSW you will). You might also learn things about making statements about "all" things, "some" things and compounds of all these things. Yeah, you can't say whether the rotten apple's brown or not. However, you can conclude that if the...

    Uni Education - Makes you a better person?

    :) I dunno! Probably. But it formalises logical implications and teaches you how to draw valid conclusions, not bogus ones. Here's a question from a past maths exam paper (yes, a MATHS paper!): "Brendan and Angel are characters in a TV series. Dedicated viewers of the series know that...

    Uni Education - Makes you a better person?

    Wow! Did you notice that your statement is recursive? Or at least self referential! :p Look, not to make friction, but it's not true that my argument is not true. Yes, as you said, some people in the forum go to uni yet act like you say. But for all you know, they might have been worse if...

    Uni Education - Makes you a better person?

    Incidentally, a lot of you guys engaging in this discussion and finding it stimulating to exchange points of view and debate in this forum go to uni. Doesn't that say something? Don't you think education DOES make you a better person in this sense? At least you can express your opinions in an...

    Uni Education - Makes you a better person?

    The very fact that the UAI is a rank shows that it's intended for there to be classes in society. Schooling is the process of separating us into our social castes - we're all just part of an experiment, I tell you! However, every class is a necessary part of the complete system. Whether you...
