Good luck guys

that was kinda funny lmfao they wrote some nice creative writingsAfter Q14 im![]()
yeah it was like a really abstract test that’s a good way of putting it but for the most part just going through with calculations got to the required result so I think it’s ok- predicting a very low E4 cutoff this year though so don’t be too disappointedSo kind for a student who just came here for two years, questions are abstract and see you E4.......
Can I ask you about how many marks you think you got?What do you guys think the E4 cutoff will be?
I spent like 20 minutes on that and I finally got it after just staring for so longI could not do that stupid square question for my life
Bruh how, q16 b took too long I gave up on itI spent like 20 minutes on that and I finally got it after just staring for so long
you can write “vector” CB = e^(ipi/3)CA since it’s equilateralBruh how, q16 b took too long I gave up on it
moments before disasterGood luck guys
@tgone wtf they actually asked the same question as this in this year’s HSC (with minor variations)….Check out Q6a) from 2005 HSC…
yeah literally i looked at it in reading time and did a double take … thought what the heck did he know about it… so glad i did it thank you so much@tgone wtf they actually asked the same question as this in this year’s HSC (with minor variations)….
although to be fair when you sent I just skimmed over it and thought yeah I think I can do this after a bit of thinking so it just made it quicker in the test rather than letting me know how to do it@tgone wtf they actually asked the same question as this in this year’s HSC (with minor variations)….
Same lol it took me by surprise when I first saw it, thinking about how it looked really similaryeah literally i looked at it in reading time and did a double take … thought what the heck did he know about it… so glad i did it thank you so much![]()
QuestionTo try find the substitutions the trick is often to try match up the powers. For example, if I was like prove that a^4+b^4+c^4>abc(a+b+c), you see the 4th power so instantly you're thinking along the lines of Am-Gm for four. Then, you see three terms on the LHS and you notice that on the RHS you've got a^2bc, so a is twice the power. Therefore a good guess would be Am-Gm for a^4+a^4+b^4+c^4≥4a^2bc. And you'll find that this works out if you to it for b and c and add them together. Like fr it's tricky but there are some hints in the question itself and it helps you narrow it down to like a couple guesses. Idk if this helps
