    Mathematics Extension 1

    a) An odd function is defined by f(x) = -f(-x). At x = 0, f(0) = -f(-0) f(0) + f(0) = 0 (since f(0) = f(-0)) 2f(0) = 0 f(0) = 0, as required. b) Take any odd polynomial P(x). By the remainder theorem, P(x) is divisible by (x + 0) if P(0) = 0. From (a), we know that for all odd...

    Poetry English Advanced

    Enjambment is pretty much whenever there isn't a punctuation mark (comma or full stop) at the end of a line. Eg The wind rose high As if a thousand eagles were sailing through Enjambment: the sentence continues onto the next line

    Clarification on simultaneous equations.

    Here's how it works if you have 4 equations 1, 2, 3 and 4: Use equations 1 and 2 to make equation 5 (3 unknowns) Use equations 3 and 4 to make equation 6 (the SAME 3 unknowns) Use either 1 and 3 or 2 and 4 to make equation 7 (the SAME 3 unknowns). Now you have 3 equations 5, 6 and 7. Use 5 and...

    Help with Geometry proof

    Construct a line parallel to the other two through x. Now x = 12 + 49 (alternate angles with parallel lines, adjacent angles) so x = 61 degrees

    Question on sorting HELP?

    Insertion and Selection sort both require the 'shift' manoeuvre (when you insert an item into the array and 'shift' the rest down). This means they are quite inefficient on large amounts of data and are better done using 2 arrays (one for the unsorted pile, one for the sorted). Bubble sort is...

    Length contraction

    A and B mean you are in the same reference frame as the spaceship. C and D mean you're on Neptune, E means you're on Uranus. "L is the length observed by an observer in relative motion with respect to the object", that means travelling in any direction. so in A you're moving TOWARDS...

    Need 98.5 UAI equivalent for course

    Aww wow... Thanks :) Everyone on here seems so clever though... But I haven't been browsing for all that long. Oh, and I forgot to mention something! 4u and 3u get doubled to 2 units or something... So it still counts as 4 units of maths, even though my 2u mark is rejected... Can't remember...
