new solution



dividing everything by t and simplifying:






or

is this correct or are there specific values for theta in this range

i thought the question said there are 2 theta values you need to find not a range

Two times didn't give a restriction on theta

hm fair enough i just solved for theta values but believe had the same a similar eq at some point then everything like the u's, g's etc cancelled and i got theta =0 and some other exact value

Hello Everyone, I am currently doing maths ext 2, will be having my HSC in 2022, any advice for me to keep in mind along the year. I do go to a school ranked in the 100s.

Work hard, think about concepts deeply and most of all...

Enjoy it! Extension 2 Maths is a rewarding journey for those who put effort in, irrespective of what your final mark is.

It will most likely take up the most time of your subjects (and should rightly so as it will comprise of 40% of your entire HSC). It is definitely rewarding with its alignment in the HSC, but that doesn't mean you should RELY on it. As said above, put in the hard work (a consistent grind), even if it is just 1/2 to an hour every day (past exams, questions, homework, etc) and let the scaling do its 'magic' for you. Youtube videos are a great source (sometimes not given enough credit by people), especially people like Eddie Woo, who explains many maths topics in such great depth and very concisely. It will be challenging, but stay perseverant and you will be able to reap the benefits from it.

You are correct, so that means there should be open circles at and at and the boundary along the real axis between them should be dotted.

Good catch!

DS did actually realise both of these properties which made him think the region was much more complicated than it turned out to be, so time ran out before he started on the proper graph. He has a lot of rough workings & sketches, but no idea whether they'll count for much. Overall, he thought it was a good paper which explored mathematical concepts to more depth than previous years, but he is fortunate in having the luxury of sitting next year's paper if he's not happy with his final mark.

who is ds, are they accelerated?

Luxury yes and no

My ‘dear son‘ who is in Yr 11 & only accelerated in maths.

wow he must be bright if he wasn't at the least slightly perturbed by the exam

I only thought there were certain subjects you could accelerate in Year 11 (like Modern History, IPT, Business Studies, etc). I've heard of 4U students accelerating 2U in Year 11 (which obviously won't count for their HSC but can help the current Year 12 current), but never people accelerating 4U and 3U. When would they learn the Year 11 content?

It’s offered at certain schools depending on the child a lot of the time. You don’t “miss out” on the year 11 content you just start it a year earlier with the cohort above so in effect skipping the year 10 syllabus content.

Would they have to do accel 3u alongside accel 4u?

 

[dbramley]

Would they have to do accel 3u/2u alongside accel 4u?

Yep start of with yr 11 2 and 3u and either choose to pick up 4u or leave it till their actual hsc year and only sit the 2,3u exams early.

got a friend who stated year 11 content in year 9, and she did her 3u and 4u hsc last year when she was in year 11, and the rest of the hsc exams she did this year with us. Actually in my current 3u and 4u class there s also a girl in year 10 but doing 3u and 4u exams..

I’ve always assumed from your profile & posts that you too have been accelerated in maths.
Extn 1 can be studied in parallel or before Extn 2; the preliminary (Yr 11) course must be completed before either can formally commence.

the trick is to not be intimidated

because of my traumata i rarely get intimidated which massively helped with blitzing through maths

actually this is really helpful. i couldve easily got 4/5 for that projectile question if i wasnt so anxious at the fact it was a 5 marker in q16 which screwed my algebra and expanding. gotta apply that to x1 now.

It's interesting, because from the school I went to (a top 10 selective school), they never offered any options of accelerating maths. Is it something which the top selective schools just don't offer (like Ruse, NSB, NSG, BHHS, etc) or does it depend on the school and the calibre of the students?
