    Polynomials: Schur-Cohn Criterion.

    Well here's my attempt at the first one. $We have the polynomial $ p(x)=x^2 + bx + c $, where $ c $ and $ b $ are real.$ $Let the roots be $ \alpha, \beta $ such that $ |\alpha| < 1 $ and $ |\beta|<1. $From sum and products of roots, it follow that $ \alpha + \beta = -b $ and $ \alpha...

    Are the coefficients real?

    Cool problem of the day!

    Yeah, and it was a lot of fun to do too. I am doing the first one now, so far got the z direction coordinate to be \frac{ln2}{3}

    Cool problem of the day!

    Is the answer to the first one (\frac{\pi}{4},\frac{ln2}{2})

    A few thoughts on Mathematics

    I had him for discrete this semester, I really liked him.

    eV?

    As stated above, 1eV = 1.6 x 10^-19 J eV stands for electronvolt, it's just another unit of energy, but it is related to an electron. You could use joules, it doesn't matter.

    Should be easy question

    I'd say sin[(2x+1)y]

    Help with mechanics question please

    It's not hard, it is fun though, was probably my favourite topic in MX2! When you first look at it, it looks hard, but when you do it it's not really :p

    I know what I did wrong.... fixed it.

    Help with mechanics question please

    When the car is going down the hill, the forces acting upon it are F=mg(\frac{1}{30}) - kv_d^2 \\ $The car is travelling at a constant velocity, and so $ F=0 \\ mg(\frac{1}{30}) = kv_d^2 \\ k = \frac{mg(\frac{1}{30})}{v_d^2} Now that we know k, we have everything we need to find the force...

    UNSW Exams in a Marquee??

    Tents were fine, very warm. I was just in shorts and a t-shirt and I was fine. They have air conditioning running through it to heat/cool the place.

    Finals coming up >:(

    Q3 was weird. I got an answer for it, but I managed to do all of it in about a page, which leads me to believe something went wrong...

    UNSW Exams in a Marquee??

    Yep... physics was delayed for an hr..

    Finals coming up >:(

    Not to bad, question 5 was annoying because it made me draw 5 sin waves -.- And it got delayed for an hr for some reason. Something about power failure in some other tents, so we had to wait so we all started at once. But the other 1131 group started on time so Idk...
