Got an offer into B Business/ B Computer Science, really happy about that, can't wait to start uni!

'The Gods Must Be Crazy' - don't watch it, just trust me on this one.

Could someone please explain to me why we can find the maximum of h (in part (ii)) by simply working it out like so?3 - 0.4h > 0 - 0.4h > -3 h < 3/0.4 h < 7.5 m How does the discriminant (I'm assuming that's what we're doing), give you the maximum? Thanks, DJel.

Hi, I was just wondering if we have to factor writing our numbers on each page into the exam time or we can put them on straight after the exam? Are there any set rules about this? I always thought we could but during trials one teacher noted that we need to account for them in the exam itself...

Here's a good online store for headphones: www.headphones.com.au Also, they have a forum with recommendations: http://headphones.com.au/forums/viewtopic.php?t=7

Probably just a troll.

I think most subjects have their challenging aspects. I have friends who do visual arts and I don't see it as a 'soft' subject. It just appears that the OP associated 'soft' subjects with low scaling, "despite their woeful scaling", and failed to note visual arts on her list although it receives...

Do you do Visual Arts as it says in your profile or is it a mistake?

Thanks for that solution. Also, I am having a bit of trouble with the short way of finding the greatest coefficient. I know how to expand them out and find the greatest coefficient, however, this just wastes time. What would be the quickest way of doing a question like so; "Find the greatest...

Good work... :rolleyes: Thanks for that. I was unable to find a definitive proof and assumed this was so the formulas would work out.

Could someone provide a proof for why 0!=1?

Could you send me a link to the figures about this?

Question: "By equating the coefficients of (1+x)10 and (1+x)(1+x)9, show that 10C4 = 9C4 + 9C3" I understand how to get the coefficients of (1+x)10 and from that I can show the relationship using factorial notation. However, I'm unsure what to do with "(1+x)(1+x)9". Thanks, DJel.

How ignorant and narrow-minded can you be? There is nothing wrong with the quality of major works coming out of the public system.

I believe they would. Plus, I'm not looking for "very high level" questions.
