    Higher Maths and course troubles.

    In some math subjects (not MATH1131/1141), they do cap the maximum mark of lower subjects. But for maths subjects with lower and higher versions, most of the high distinctions they allocate are for higher version students (due to the quality of these students). So if you are good at maths...

    Parametric equations of Parabola - Need help

    Easier way than distance formula: Remember the fundamental fact of the parabola: distance from any point on the parabola to the focus = perpendicular distance to the directrix. Noting directrix is y=-a, so: PS = distance to focus = perp. distance from P to directrix = ap^2+a (draw a diagram...

    Quick simple question - What is the difference between to graphs??

    sqrt(f(x)) by definition is always positive, so if g(x)^2=f(x), then sqrt(f(x))=|g(x)| Consider a numerical example: 2^2=4 also (-2)^2=4 but sqrt(4)=2 = |-2| =|2| rather g(x)=+sqrt(f(x)) for some values of x (in this case x>=1), -sqrt(f(x)) for other values of x (in this case x<=1)

    Help me choose my courses for Commerce/Science first year.

    First year maths course => Do MATH1131/MATH1141 (1141 if you want to major in Physics and computer science) - for more information, go to unsw maths website If you major in physics and computer science you may need to do MATH1231/MATH1241 as well. If you want to do computer science, do MATH1081...

    Quick simple question - What is the difference between to graphs??

    +sqrt(f(x)) must be greater than or equal to 0 for ALL x. So: +sqrt(f(x))= +sqrt((x-1)^2))/(x+1)^0.5 (x+1)^0.5 is always positive by definition Consider +sqrt((x-1)^2) <-- this must be greater than or equal to 0 for ALL x. So if x-1>=0, then +sqrt((x-1)^2)=x-1 If x-1=<0, then 1-x>=0 and...

    Physics Help Please: Projectile Motion

    Only consider vertical direction (up/down) as you will not deal with any horizontal forces in projectiles. It actually does not matter which direction is positive, as you just label anything going opposite to that direction to be negative. But for convenience sakes, do as you have said.

    My second degree: Arts or Commerce?

    1. Prob not as you wont have enough units of credit to do so. 2. It is a 5 year combined degree, with honours (in maths) in the 5th year

    Watson captain for sure

    Watson played an awesome anchor role, but M Hussey's little cameo was the one that really kicked started the chase and gave Aus the chance to win.

    My second degree: Arts or Commerce?

    Arts: - More interesting than commerce - learn some languages - Cheaper to do arts courses than commerce courses - Allows you to take up education courses if you decide you want to teach Commerce: recommended majors (Finance, Actuarial studies) - Gain some background knowledge if you decide...

    Another Complex Number Question...

    Suppose y=0, then z+1/z=x+1/x=k so |k|=|x+1/x|=|(x^2+1)/x| we use the basic inequality of x^2+1>=2x (Based on (x-1)^2>=0) Then |k| = |(x^2+1)/x| >= |(2x)/x|=2 so |k|>=2 Suppose x^2+y^2=1: Then |x|<=1 (as x and y are real numbers) so subbing (x^2+y^2=1) into the equation for k will give...

    Complex Numbers Question...

    (a) Let P(x)=px^4+qx^3+rx^2+sx+t where p, q, r,s, t are real P(a)=0 implies pa^4+qa^3+ra^2+sa+t = 0 Show P(conj(a))=0 Sub into P(x), use the fact conj(a^n)=conj(a)^n, pconj(a)=conj(pa) if p is real. try it yourself
