Oh I didnt see that they accelerated Bio, yeah you should probably keep Biology then, but I still reckon you should drop SOR I for Economics.

What your supposed to do is, after you enter the formulas for all rows in D and E until row 11 Enter the a's b's and c's of the questions they gave you For a), put in the second row a=1 b=9 c=-10 Do this until j, you should have your solutions according to excel By the way, they gave you the...

In my honest opinion, assuming you will be doing 4U math in year 12, you should either: 1.Drop Biology for Economics 2. Drop SOR I for Economics Alot of people will tell you to pick what you like, and in general that is what you should do because the theory is that if you do subjects you like...

Please do not even try 500 past papers for each subject, thats like 2500 papers minimum in 365 days, so you will be looking at about 8 papers per day, all of which are 2 hours +, so at an extreme minimum of 16 hours a day for only past papers, add in 6 hours of school, and you will have 2 hours...

If I could turn back the clock I would of studied harder for 2u and 3u math hye for hsc...

What is your atar aim?

Re: ITT we help examine to get 85 in his Maths extension 1 yearlies so he can do 4 un P(2ap, ap^2) \ \ Q(2aq,aq^2) \\ m_{PQ}=\frac{ap^2-aq^2}{2ap-2aq} \\ m_{PQ}=\frac{p+q}{2} \\ \\ eqn_{PQ} \Rightarrow y-ap^2=\frac{p+q}{2}(x-2ap) \\ \\ y=\frac{1}{2}(p+q)x-apq \\ \\ $Intersects with directrix...

If you are competent in maths, then out of Chemistry and Physics, Chemistry is harder, if you arent that great at maths, then I would say Physics is harder. Do both if you can imo

y=\frac{x-2}{x} u=x-2 \ \ u'=1 \ \ \ v=x \ \ v'=1 \\ y'=\frac{1(x)-1(x-2)}{x^2} \\ y=\frac{2}{x^2} Another way (faster) y=\frac{x-2}{x}=1-\frac{2}{x} \\ y'=\frac{2}{x^2}

Finished MX1 this year, came second, next year an aim of 1st EDIT: Thanks guys for the estimates, I really appreciate it (it also made me a bit happier too)

Hello, Im just going to list a series of ranks for which I aim to get. Atar Aim: 99.95 (happy with anything 98+ but this is the real goal) School Rank: 100ish 4U Math: 1/4 3U Math 2/20 Economics: 1/15 Chemistry: 3/40 Physics: 3/40 English Advanced: 2/25 English Ext 1: 2/10 4U Math: 1/4 3U...

Well of course there has to be good parts Chemistry, and whatever is good in the Chemistry syllabus, I love it. Not this socio-economic Chemistry, or Physics-History etc etc

Re: Math help (Because Carrot made me do this) Oh yes hang on I read it wrong...oops. So: y=a_1 x^n+a_2 x^{n-1}+...+a_{n+1} Where the a's can be any number (real, complex), so this polynomial must have at least 1 complex root? Thanks for clarification

Re: Math help (Because Carrot made me do this) Well it was a joke about the rep, if rep was still back, my motivation for posting would be because Im bored, I want to benefit my own understanding by teaching someone else, and I want to help. Rep is as it always should be, a positive...

Hah, Im not saying the Board of Studies is always right, I reckon General Maths should at least be compulsory (in my opinion). I mean look at the horrible science syllabuses (syllabi?), its a good representation of the incompetence of the Board of Studies. They also restrict english as well...

Yes but then can we all say, 'hey people doing higher maths, your doing useless subjects that are useless to your life because you never need to know how expand binomials, or understand calculus or whatever, General maffs is the real stuff' The point is, the subject of maths is there in order to...

Re: ITT we help examine to get 85 in his Maths extension 1 yearlies so he can do 4 un So what we need to do, to find the focal length, is to get the equation into the form: (x-h)^2=4a(y-k) Where a is our focal length: y=x^2+6x+5 \\ y-5=x^2+6x \\ y-5+(\frac{6}{2})^2=x^2+6x+(\frac{x^2}{2}) \\...

No, they make English compulsory because you pick up skills in it that can help you in real life, do you think a job interviewer will accept you if you speak like a monkey? If Im going to be completely honest with you, for the benefit of your cohort, drop to standard, but because you shouldnt...

Re: Math help (Because Carrot made me do this) 1. It can be any value you like I was using them as examples, so if you want to find the y value of the final function at x=1000 Then we do f(1000)+g(1000), and we see what we get. 2. When f(x)=0, this is the x-intercept its the same thing as...

5d) Ignore this if you know why a parabola is a parabola Cool way: We know by definition that a parabola is a locus of a variable point, where the distance from the variable point to a fixed point, and the variable point to any other variable point on a straight line is the same: This fixed...
