Re: Don't quite understand a concept of integration - conflicting concepts - need hel the reason why you have to split it up is because one part of the graph is below the x axis. If this occurs, you cannot simply calculate it by substituting the values because you could get a ZERO or negative...

Re: Don't quite understand a concept of integration - conflicting concepts - need hel if you are told to integrate, then the answer is 0 if you are told to find the area, then the answer is 8 units^2

Re: it is possible to get 100 in any subject as a HSC mark right. which is 50.0 scale some subjects are capped. e.g. standard english, general maths

^ I'm in same situation. 99 in exam, 98 assessment

it's preliminary - it should be fine. it's only the first few weeks of Year 11 - the teachers should understand why students change. the only reason they have to reject you is timetable clash.

definitely learn ahead! this will help you a lot during Year 12 - you will be doing past papers whilst your classmates are still learning the material. as you are in Year 11, make sure to try out different study methods and see which one works for you. Dont stress too much -make sure you study...

yes harder 2unit is part of 3u. but its easy

it worked for me.. it kept me motivated. as long as it helps you, then do it!

Re: it is possible to get 100 in any subject as a HSC mark right. which is 50.0 scale they don't look at the mark. they look at the rank. so say if 17/20 was the top mark, and you continue to get top mark, then you are first place. then say you score 100% in 3 unit exam, ranked 1st - scaled...

nice work in maths. 83/84 = 52 state rank so I wonder how many 84/84 there were and how do they select top 10 out of the people who scored 84/84

yeah I got this award i think selection is sort of biased

easiest would definitely be Differentiation or Algebra LOL Hardest would be Permutations and Combinations. Parametrics is not that hard. Exam questions on Parametrics do not get too difficult. If you do Conics in maths Extension 2, you'll totally kill Parametrics. Conics is a devil to deal with...

lol i had mx2 in morning and afternoon. Having mx2 at lunch sounds fun! haha are you allowed to eat?

Pyrobooby, if you gain first internally and externally, you take your own exam mark. Let's say you get 95 in the actual hsc exam. your examination mark will be 95 and your assessment mark will also be 95 (since you're the top student in your class, you take the top examination mark which was...

^ your class can't damage your ATAR IF YOU DO WELL! If you come 1st in English Standard, the class DOES NOT pull you down (unless you do shit in the actual exam).

2) find the equation of a hyperbola with eccentricity 5/4, focus (-10,0) and directrix x=-32/5 ae = 10 a x 5/4 = 10 a = 10 x 4/5 = 8 a^2 = b^2(e^2-1) 64 = b^2(25/16-1) 64 = b^2 (9/16) b^2 = 64 x 16/9 b = 32/3 (i think) didn't use calculator and then plug into equation

haven't touched this stuff in agessssss. I'm starting to forget. correct me if i am wrong LOL

1) foci are on x axis. ae = 10 b/a = 4/3 b^2 = a^2(e^2-1) b^2/a^2 = e^2 - 1 16/9 + 1 = e^2 25/9 = e^2 e = 5/3 (e>0) a = 10/e = 6 b/6 = 4/3 b = 4/3 x 6 = 8 equation is x^2/36 - y^2/64 = 1

can't wait until they put up another tutorial for Foundations of Law (GRRRRR) who wants to go to uni for one hour just for LAWS1052? I want 3 days of uni NOT FOUR
