Yep. There was even a discussion about it on the ext 2 hsc thoughts thread. You can absolutely use past HSC exams from previous syllabi, just make sure the content is related to the new syllabus.

It's an electronic exam 🤮. I mean I know it's a technology subject, but it still feels off to have hsc exams be electronic.

Correct. Put that in the denominator of the fraction and you can get the RHS result required.

It should be available somewhere in students online. I very clearly remember that I was able to download my results as full page pdfs when I did min standards in 2020.

We are analysing SHM that begins at the maximum value and then begins to decrease. We can model this using a cos graph. Period = 12h40m = 38/3 hours. n = 2pi/(38/3) = 3pi/19 Range = 6m, therefore amplitude (a) = 3m The centre of motion is 6m so c = 6 Setting 5am to t=0, then the value of alpha...

I did. Is it exclusive for high-performing students or just a gimmick they actually send to everyone?

Eco 94 Eng adv 87 MX1 95 MX2 93 Phys 91 6 months ago i wouldve never envisioned a b6 for phys, so this is pretty great

If I get a bad ATAR.... it was those motherf*cking staples I swear.

It is created by the very authority that actually performs the scaling of the subjects... so pretty much as accurate as it can get. The limitation comes from students not being able to know what their hsc subject mark will be, and scaling differences between years.

For inequalities, write out what LHS - RHS is and then prove that it is > or < 0 as required, since proving that a function has a certain sign is much easier than proving the inequality directly. Also, proofs is a new topic, but was segmented and tested in old syllabus papers. You can get...

What subject are you trying to change? Don't worry about the term nearly being over because you are allowed to drop at any point during Year 12, it's only an issue if you have some sort of assignment over the holidays.

I won't tell you with certainty that you should switch. However, if you do, you'll find a lot more online resources and discussion for 1984, which will be beneficial and might inform your decision.

The terms on the LHS are the arguments of (1+3i), (1+5i) and (7+4i) respectively. Taking the products of these gives -130, which has an argument of pi. Using arg(xyz) = arg(x) + arg(y) + arg(z), the result is proven.

Don't get an idea of physics as just being another 2 units of math. There's definitely calculations, however a huge part of physics success is also understanding concepts, providing reasoning for explanations, interpreting data and comprehending large ideas of information that reminded me of...

Definitely wrong. Multiplying both sides by (t-1) shows that the LHS would be a (n+1) degree polynomial, while the RHS would be a n degree polynomial. If you sub in 1 the LHS would be (t+1) -> n is the degree of the highest power of t in the LHS.

A more simple method is to consider a linear equation that passes through (0,r) and (h,R). If you rotate it about the x-axis, with boundaries of 0 and h, it will produce the frustum with the dimensions and variables required. Use the cartesian equation of a line to show that the function would...

Yeah pretty much. I used a calculation to show that the illustrated velocity is nowhere near what the actual orbital velocity would be, and then a sentence to consolidate that the hypothesis is wrong

So in the exam I considered talking about speed... but the question very specifically asked about the path not the motion. Will I lose a mark for that? Also aren't charge and direction the same linked concept? I discussed that X and Y had to be positively charged and Z negative by RHR.

9:25am, give or take a few miniutes /s In all seriousness, they usually take 2 business days to upload it officially to the nesa website. Though you can look for shady versions on the conquer server.
