    Wooo we have our own club now, complete with two cross dressers and a bi-polar disorder sexual harassment suit in the making.

    And a Limecat.

    Wow aren't we lucky

    Crap. My computer is very possibly screwed. Typical, technical brother just gone back to uni, father away. MSN advice from brother failing.

    Not happy.


    There's a cheerful and related contribution for you.

    TITCUMB IS MY BABYYYY!

    Dani told me to come to the Insomiac thread, so here I am .

    A curve has equation y = x^3 + 6x^2 - 36x + 25.
    Find the exact co-ordinates of the stationary points of the curve and determine their nature.

    dy/dx = 3x^2 + 12x - 36

    At the two stationary points, dy/dx = 0, hence:

    0 = 3x^2 + 12x - 36
    0 = (3x - 6)(x + 6)

    x = 2 OR x = -6 at either of the stationary points on the curve.

    For the point where x = 2: y = (2)^3 + 6(2)^2 - 36(2) + 25
    = 8 + 24 - 72 + 25 = -15

    For the point where x = -6: y = (-6)^3 + 6(-6)^2 - 36(-6) + 25
    = -216 + 216 + 216 +25 = 241

    To determine their nature, find the second derivative of the curve's equation and then sub. in the two values of x, in order to determine the nature of these two stationary points which have these x-coordinates:

    d2y/dx^2 = 6x + 12

    Sub in x = 2 into the above: d2y/dx^2 = 6(2) + 12 = 24 ----> +ve value ----> (MINIMUM POINT)
    Sub in x = -6: d2y/dx^2 = 6(-6) + 12 = -36 + 12 = -24 ---> - ve value ----> (MAXIMUM POINT)

    Solutions To Question:

    * There is a stationary point on the curve at (2, -15). This is a minimum turning point.
    * There is a stationary point on the curve at (-6, 241). This is a maximum turning point.

    if he doesn't marry Gemma he's marrying me so I can divorce him and keep his name. I also gave the Of Mara CD to Bruce Dickenson and he loved me forever for that!
