Re: The Official Football Thread Why?

This is a good idea. Our 4U test didn't have any MC though so I can't help :(. Hopefully our next assessment +trials have them.

This is actually a good way to test whether you are correcct. Ideally though, use a bigger number :)

In what context lol?

wolframalpha.com- This is the best website for maths (especially for confirming answers for integration, differentiation, algebra etc.)

Depends on who you are. For me, anything - classical, soundtrack, pop, electronic etc. Most people however find that they can only work to classical music so maybe try that.

youtube.com- Don't underestimate the power of a good song to study to.

How bad did you fail, what are your current ranks and what is your school rank?

This should be -5/2 and no, not neccessarily

What school do you go to? Last year, someone in our school made 1 mistake in 4U in the whole year- he state ranked.

Yep. That's the question. Here it is (if you guys can get part ii, then you should be set for maxima and minima): Sorry for not making the picture appear (I still can't do that haha)

This is similar to a hard 3U question from the 90's or early 2000's. I'll track it down and post it so you can have a go.

Probably the same answer as mine. I didn't look at the calc properly, just the digits in front of the decimal place so you'll be right.

Yes because both sides are positive.

Is v 109 km/h. I rushed through it so I wouldn't be surprised if its wrong... Its a good question though.

This is off the top of my head, so I've probably missed some steps. If you give a quick problem, I can solve it and then list the steps if I missed stuff: 1. Write out all the information. For example, if its a cylinder minimisation problem, write the equation for the volume of a cylinder etc...

I always bring water bottles... As if you're school doesn't let you?

I'd train and become a world class bored of studies poster :). Seriously though I'd probably still become a corporate lawyer.

I've still got 12 and I find it fine. Having said that, I like all my subjects. Others in my year that dropped eco (they didn't like it) say that its way better for them now.
