It's only BOS trials

3u seemed a bit harder, but I'd say 4u was very doable.

Who was the guy that gave up and started reading his novel at the last hour of the 4u lmao.

I thought the 4u was easier this year

Gonna stop by, since i have to come USYD anyway.

Re: Semester 2 USYD Chatter Thread Yeah, would be interested

Re: 2015 permutation X2 marathon I has 4 pairs of different coloured jelly beans, if i place these 8 jellybeans in a row, how many different arrangements are possible if no two of the same coloured jellybeans are next to one another.

re: HSC Chemistry Marathon Archive Breaking bonds don't release energy.

I don't think any people that haven't actually completed their HSC can comment on this. I brought my exam response and for the most part, all the marks i lost were fairly justified. It just comes down to not answering the question or giving just a straight out wrong response. If your asked to...

Re: HSC 2015 4U Marathon Solve for k, (8-3/k)(1-e^(-k))=1. Not sure where this belonged.

Isn't it defined by i^2=-1 rather than just i=(-1)^1/2 alone?

Re: MX2 2015 Integration Marathon You need a surface area formula for integrals for part b and comparison test, that's easily googleable though.

Re: MX2 2015 Integration Marathon Here's gabriels horn from my tute if your interested.

Re: MX2 2015 Integration Marathon Yeah i can see the problem with the integrals now. It just seemed intuitive that you can just multiply into the integral since you've done that without any thought in HS math.

Re: MX2 2015 Integration Marathon Yes it's a constant.

Re: MX2 2015 Integration Marathon It's a question from my MATH1903 assignment, had to use epsilon delta continuity arguments, limits and the Riemann integrability definition.

Re: MX2 2015 Integration Marathon Why couldn't math just be made simpler, i mean like, i'm trying to show this Dunno what mathematicians see, but that looks pretty obvious enough to me :(

Sausage fest tbh, especially in any physics class.

ON was it you fiery passion for CAG's that started the fire?

re: HSC Chemistry Marathon Archive Change in pressure doesn't necessarily mean increase in temperature, look up isothermal process. Even if pressure increases temperature, it's doing it indirectly and in the end your still arguing that it's temperature that changed the equilibrium constant...
