You mean 20 or so. :P @maddyyy: Hahaha at first I thought you were a girl from my school because she did almost the exact same subjects as you and her name's Maddy. Congrats for the great results!

f(x) = y = ax³ + bx² + cx + d f'(x) = 3ax² + 2bx + c For stat pts, solve 3ax² + 2bx + c = 0 .: delta = (2b)² - 4(3a)(c) = 4b² - 12ac Require delta > 0 for 2 distinct solutions. i.e. 4b² - 12ac > 0 4b² > 12ac .: b² > 3ac Now, having turning pts at (0.5, 1) and (1.5, -1) has implications...

To find turning pts - solve dy/dx = 0 dy/dx is going to be quadratic equation, by the looks of it. For a quadratic equation to have two distinct solutions (i.e. for the curve to have two distinct turning points), the discriminant (i.e. delta) must be greater than zero. I'm late for work - I'll...

No that doesn't seem right at all. A friend of mine did similar subjects and got all low-mid band 5 plus a high band 4 and still got 83.xx UAI. Definitely ask UAC to explain.

The maths syllabus, unlike those for other subjects, isn't clear-cut between Yr 11 and Yr 12 topics. It's actually titled the "Mathematics 2U/3U Year 11-12 Syllabus". You can think of the topics/modules in other subjects as distinct blocks, but in maths you should think of them as layers (and...

Re: Premier's Awards...? ^ Neither did I. Haha. My principal mentioned something about a ceremony at school with the mayor/MP/etc. Maybe we'll get the hunk of glass then? I don't mind a hunk of glass. :D

Thank you. I heard the rumour from a friend who was invited to the B Mus/MBBS interview with a UAI of 99.65. Oh well, doesn't matter now. I was trying to find out before the UAIs came out. (And you're right about too many 99.95-100.00 apps. I know of another 3 people who got offers for B Sc...

Yes, lol.

I think sitk meant s/he sat the HSC exam for IPT in Yr 10, but because s/he plans to take MX1+MX2, Mathematics is excluded although it was studied in Yr 11. And my advice is to rid EE1 and another 2 unit subject. See risole91's comment.

A bit late for you maths assignment, but just in case you still wanted to know the solution: Let's find the points of intersection of y = 10x + 10 and y = Ax² by solving the two simultaneously: Ax² = 10x + 10 Ax² - 10x - 10 = 0 Now, keep in mind that for the line y = 10x + 10 to be a...

Ah. I see you're also a fan of Ctrl+F. And you're right in your inferrence. I find it an immensely fascinating field, but at the same time I often find myself lost in it. Reading bits and pieces on arxiv only helps so much when I haven't thoroughly built an understanding from the ground up. I...

The process you're talking about here is "aligning" not "scaling". Giles Gardam (1st in NSW) reckons he got 120/120 = 100 exam mark. My friend Sunny Wang (9th in NSW) reckons he got 118-119/120 = 99 exam mark. According to Terry Lee's solutions I should have got 118/120 as well but since I...

I was going to ask, but I did a little Ctrl+F on the top achievers list. 5th in Cosmology is bloody fantastic! Well done! @ xclusv2bhung: Thanks! I hope everything went well for you, too.

My friend ranked 10th in business with 98.

I just got a call from USYD. I've been made a formal offer for B Sc (Adv)/MBBS plus $10000/yr for the duration. I never could've imagined the offers to be made this early.. I mean, I only had the interview yesterday! How did you go?

Hahaha! Thankfully it's one I can deal with. I'll let my two out-of-nowhere state rankings make up for that 0.05 imperfection. Now, care to let us know what UAI you got? You're bound to have more than enough for Com/Law at USYD.

NSW UAI: 99.95 SAM: 100.00 JUAI: 100.00 Einstein: 100.00 Oh this is funny. I'm very very happy about my UAI - although there is the slight irritation that comes from marginally missing out on 100.00, especially when my HSC marks for two subjects were lowered by assessment marks. Still happy...

Lol just checked.... 99.95, lol. Damn school assessment marks dragging me down! I'm still very happy about my UAI though. Burwood Girls High School.

Well done everyone! @ari89: With those results you're bound to overshoot your aim by miles and miles and miles!
