Id say high 98s, 99 if you can do well in the Maths External.

Looking at our question: 9^x-4 \cdot 3^x+3=0 We need to find a way to which we can solve it using the algebraic methods we know, its obvious that we need to bring this to a quadratic form: In order to get it into quadratic form we need to have something squared and something. We know that...

Re: Math help (Because Carrot made me do this) If you still remember our 'formula' I posted to calculate horizontal asymptotes. I left out what happens when n > m because that is covered in 4U. Basically when n > m you must use polynomial division (or otherwise) to find the oblique asymptote...

Re: Math help (Because Carrot made me do this) D94 was simply displaying a creative technique in simplifying the fraction into a form where we can get our slant asymptote. You can just do normal polynomial division of x-2 by x^2, the thing you get ontop is your oblique asymptote, (ignore the...

Re: Math help (Because Carrot made me do this) Where did you get this question? Tutor or book? Finding the asymptote to this one is harder because it introduces a slant asymptote. That is the inclined asymptote, which is y=x in this case You must use polynomial division in this case. Ill get...

Im bored with English at the moment, so I will mention what limits are: Take my analogy for instance: I am in an unknown world and galaxy, and I set off on a road to a distant town, I can always see the town in the horizon, yet when I keep going closer, and closer but I can never ever quite...

CSSA Papers are easy for maths, try Independent papers if you can get your hands on some

Re: Math help (Because Carrot made me do this) Ill have a good explanation on what limits at night maybe, for now I need to study for English yearly tomorrow. Maybe ask another person on Bored of Studies in what limits are in the meantime? (because it can be a hard thing to grasp at first)

Re: Math help (Because Carrot made me do this) When I say negative/positive x, I mean numbers of the same magnitude but different sign. Like x=1, x=-1 will have same y-value. x=4.5 x=-4.5, same y-value etc. IF this is true for all values of x, then the function is symetrical and from it we...

Re: Math help (Because Carrot made me do this) You have made an algebraic error: f(x)=\frac{x^2}{x^2-9} \\ f(-x)=\frac{(-x)^2}{(-x)^2-9}=\frac{x^2}{x^2-9} \\ \therefore f(x)=f(-x) It is symetrical about the y-axis because it is even. The reason why even functions ARE symmetrical about the...

Which school papers would you say are some of the hardest for 3U?

Personally for yourself, do you think hand-writing notes is better than typing notes due to the fact that you understand as you right (my hand-writing is annoying to read)

Good man Spiral.

In combined medicine, when you do Advanced Science, do we have to do a course related to medicine, or can we do Adv Maths in it (because Carrot's sig is Bachelor of Science (Adv Math) or something) If so then USYD med is my aim instead of UNSW, Id like to do Maths in uni for fun, but still do...

Re: Math help (Because Carrot made me do this) I didn't really choose y=1. Its just the fact that, the higher you go, the closer our function approaches y=1. Try it yourself, in your calculator, sub in x=5, x=10, x=50, x=100. You will see that the higher we go, the closer we get to y=1. The...

Re: Math help (Because Carrot made me do this) Lets think about our curve for a second, and understand that it is one number divided by another number. We know that For all positive x^2 (which is always positive) x^2>x^2-9 . But our concept of infinity tells us, that the closer and closer we...

Is there an official reason why apparently the Math Extension 2 papers are getting easier (I have read that the newer papers are getting 'easier'). Or is this just an observation?

Mathematics Extension 2 English Extension 1 English Advanced English Extension 2 Economics Chemistry Physics Aims: 99+ ATAR State rank 4U Math

Should I rewatch two buffy episodes for Extension English yearly, or just memorise quotes and techniques (yearly is on this tuesday)

IQ matters alot for 4U math, I could grab the most eager kids ever, make them study 24/7 legit, and they would probably only get about 80+ Whoever got 100 must of been a real, real genius
