    Maths Problem-Solving Program

    And pronounced lay-tech. Please put this in the tutorial :)

    Maths question!

    Bah, with talk like that you'll make a great engineer ;) You might be right though, but I still want to have a go.

    Maths question!

    Bump. I still haven't had a go at this, but did anyone else get anywhere?

    Taking Absolute Cases

    Note my first sentence.

    Taking Absolute Cases

    Well, you can do that if you want, it is equivalent in this particular case. But in general we try and avoiding "overlapping" cases, since unless we're careful it can break the well-definedness of the function, in particular, it could lead to a map being multi-valued. For example: f(x) =...

    Homosexuality in Australia

    Mind clearing that up for me? Are you saying our law transcends God's law?

    Homosexuality in Australia

    Mate, you're an absolute fucking retard. Humans have been around a lot longer than the concept of marriage, so what are we to conclude from that fact and your statement?

    Homosexuality in Australia

    No, I do not respect you doing this, much less agree that you have the right to do so. You've setup a spectacular false dichotomy. I do not support homosexuality, I am indifferent to it but willing to defend the right of people to partake in it, and I suspect that is what everyone else here...

    Taking Absolute Cases

    You should always use greater than or equal to and less than since that is how the absolute value function is defined. That is |x| = \begin{cases}x & \text{if } x \geq 0 \\ -x & \text{if } x < 0.\end{cases}

    Graphs

    Well, how is f-1 defined? f^{-1} = \{ (y, x) : (x, y) \in f \}. \text{ So } f^{-1}(y) = x \Leftrightarrow f(x) = y. Now just take y = f(x) to see that f-1(f(x)) = x. Edit: Doh, you changed your questions :( Well I'll leave it there in case it helps anyone else. As for your new question, I'm...

    Good ol' Islam

    If Islam didn't have it's underpants in a knot over drinking and sex there would likely be a proper investigation into the rape instead of this shit?

    Homosexuality in Australia

    Why can't people have their cake and eat it too?

    Homosexuality in Australia

    Did it occur to you that maybe the desire for children is independent of which sex you find attractive? I mean, it's the only logical conclusion, but thinking and logic isn't your strong suit is it?

    Graphs

    Ok, taking a guess at what your second question was supposed to ask: g(-x) = \frac{f(-x) + f(x)}{2} = \frac{f(x) + f(-x)}{2} = g(x) So g is even. You ok to show the second one is odd now?

    Graphs

    Since f has an inverse, we have: f^{-1}(-f(x)) = f^{-1}(f(-x)) = -x = -f^{-1}(f(x)). Did you finish off the last part of your question?

    Homosexuality in Australia

    Whatever, I just think we can do better than that when arguing with a Christ bot.

    Homosexuality in Australia

    You know, I get what you're trying to do here, but it's pretty fucking offensive to label homosexuals as God's overpopulation solution. Since I'm not religious or homo, and so don't have a stake in it (no pun :P) either way, I think that says a lot.

    Rep

    Do I need to hand out rep in order to be able to receive it?
