    Mathematically...


    IT'S THE SAME!
    No. Mathematically it is equivalent.
    "Equivalence" and "Equality" are two different mathematical concepts.

    "THE SAME" is a bit too conversational for me to be happy with accepting it as just one of "equivalent" or "equal"

    I've started a monster!

    I spoke briefly to the teacher (He's actually a he, not a she). He seemed confused as to what I was saying and basically fobbed me off with a "Yes, I can see how someone could see it that way"

    My thoughts on the tangent

    "60 > 30" is read as "60 is greater than 30", but is equivalent to "30 < 60" which is read as "30 is less than 60"

    Two different ways of writing the same expression, but it does not mean that "<" = ">"
    One important thing to remember is that when you get to the end of this sentence, you'll realise it's just my sig.

    Exactly.

    I do, however, have concerns about this teacher. I don't expect primary teachers to understand advanced calculus, or imaginary numbers, but I DO expect them to have a firm grasp of the basics.

    So he's not going to correct it?

    I don't believe so, but I've told the kids that teachers are people, and sometimes people make mistakes and there's nothing wrong with making mistakes.

    No, there's nothing wrong with making mistakes, but you should also accept when you're wrong as well.

    Oooh, can I come and play? Maybe chuck a Banach space around? I've spent my day doing Runge Kutta LTE expansions! This thread is hilarious:rotfl:

    Ooooh not messed around with those for years, always preferred Adams Methods though...
    If it looks like a duck, and quacks like a duck, we have at least to consider the possibility that we have a small aquatic bird of the family anatidae on our hands

    My personal favourite is Monte Carlo simulations.

    Me too, would much rather use Adams Bashforth or Adams Moulton over RK anyday!
