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?

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}

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

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

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.

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

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

You know it ;)

There we go

I didn't use a diagram lol, that's where the error came in :p But I'll draw something up.

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

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...

I think I got it, I'll post a solution soon.

Really? O.o

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.

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...

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

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...
