Math Advanced Prediction/Thoughts (1 Viewer)

For some reason, Sydney Morning Herald always loves to make students play the victim card on NESA when there is a hard exam because their audience is some people who have never done maths for quite a long time. No surprises.

haha the crickets question

that was the stupidest thing i had ever seen

and the articles are always by the same people jordan baker and natassia chrysostomos or whatever.

Here are my estimates on whats gonna be on the adv exam

(Please don’t rely on this structure only! Its only what I think the exam could consist of from the syllabus and past papers!)

1. A multi-part Annuity/Finance Question (probs with loan repayments)
2. A pdf (Probability Density Function) question
3. A Sine/Cos rule application question
4. A rates/velocity & acceleration question (probs multi-part too)
5. The population/base of (e) question where you find the intial state and then use logs to find the power of (t).
6. A sketch the function question (where stationary points and derivatives are used) = Multi-part for sure
7. A circle or segment question
8. Various probability, integration/differentiation and series questions (two parts at most)
9. A ‘Find the shaded area’ question (alternatively linked with the trapizoidal rule)
10. A z-score/std. deviation question involving the bell curve and empirical rule
11. Lastly, a max and min question, which WILL INCLUDE a ‘show that the volume/area of the given object is....” (most likely near the end and worth the most marks)

Hope this clears up for what some people may see in the test.
Good Luck to all on Monday for the exam!

i still love how advanced is before 3u, gives me a good warm up

 

[hatterene]

contemplating on how much time i should dedicate to math adv + ext when i have a shit ton to remember for legal and business :/

depends on ranks

i would grind ext for scaling if i was ranked close to an e4 or an e4

also i'm wondering if we have to remember the awful normal distribution formula because it's 2 days before the exam and it's still slipping out of my mind

wow ew no u don't need to remember that

 

[hatterene]

then how else do you solve for the SD and mean for a normal distribution question?

z score formula

I have never seen that before in my life

 

[Trebla]

lolwut you do have to know the normal probability density equation.

I'm surprised some of you here haven't been shown that given it's explicitly in the syllabus

 

[notme123]

lolwut you do have to know the normal probability density equation....

is it on the formula sheet

 

[hatterene]

yeah it's used for sketching mainly, and finding the peak of the normal distribution graph - it was shown in maths online and the Cambridge textbook so i'd be expecting it in the exam it's just it's an unfamiliar concept tbh. it's also a hefty chunk to remember for a formula not in the sheet smh

 

[hatterene]

Where in the Cambridge textbook? Which page number?

exercise 16d - p742 (continuous probability distributions)
exercise 16e - p754 (general normal distributions)

 

[Trebla]

It's not, though I personally think it should be.

if u needed it, they'd include it in the question - have seen it across a few trial papers where they ask you do to trapezoidal rule to essentially prove the normal distribution (and they've included the formula every single time)

 

[hatterene]

Chapter 10B?

oh sorry I'm not sure about the page orders in the advanced textbook since i only have the extension 1 version. it's the "standard normal distribution" and "general normal distributions" in the "continuous probability distributions" chapter (it's next to binomial distributions in my textbook)

 

[hatterene]

also does anyone know how to insert normal probability distribution shit into a calculator? i have the fx-82 just like everyone in my grade does but when i press Shift+1 i only get 5 options (type, data, sum, variance, min/max) and my distribution option is not there

You've got enter in some ax+b data by going into mode -> stat; and then u will have a new option for the probability distribution variables (r, A, B, etc)
