ayy the maths and sciences are all pushed like 3 days forward compared to last year so slightly earlier finish

how do you reconcile integrations with more than one answer? Is the difference accounted for with differing constant 'c's? Does that technically mean any answer for an integration is correct? argh e.g. when solving rev chain and using double angle. Clearly sin^2x/2 does not equal cos2x/4...

depends which 4u class you're in - one of them is 3hrs a week - with 3:30-5pm sun and 6-7:30 thu

My younger sister wants to get into USYD veterinary medicine - where one of the admission criteria is the CASPER sjt test - is it similar to ucat sjt and if not are there any books or online packages to use for prep?

could you expand on how you got from line 2->3? (sigma notation to integral) - it looks like the sum of the rectangle areas (trapezoidal rule?) but I'm stuck how the k and n changed to become in terms of 'x'.

can you do this: \frac{1}{n}\sum _{k=1}^{\:n}\:\lim _{n\to \infty }\left(\frac{1}{1+\frac{k^2}{n^2}}\right) then \frac{1}{n}\cdot\sum_{k=1}^{n}1 which equals \frac{1}{n}?\ I'm generally not sure how to solve lim questions involving sums... please help! Thank you! *ps also noticed that latex...

dark mode is extra ass for circular pfp legends like me or @enoilgam who map the circle colour with the light grey of light mode

ok thanks for ur help! I did b) but how would you do c)? doesn't that statement imply =0: can you solve this integral without using by parts? edit: I think I would need to take the limit as t approached infinity of both sides because there is an unended ... - but I still need to learn how to...

how to do 11a)?

It all really depends on what your goal is. If it is a high ATAR course you want to get in, you basically have to accept Yr 12 will not be fun because it makes the most sense to invest most of your time into just studying so you can achieve that goal. However, if you have a lower ATAR course you...

practise the prac a lot i guess I suck at titration so I'm going to practise it by joining titration club for extra titrations. I will also pay more attention to rinsing protocol before titration so my accuracy is not compromised. Also get to know your burette stopcock (haha funi) and where it...

For step 2-4, to get better (esp with the dilution part you struggle with) make a good method and spam it with prac q before exam. My method: 1. write the equation (I find this a good first method for basically all practise questions as it's like a rote step I apply to all questions which gives...

Tips to solve STEP 1: 1. make n/c/v table - we have lots of info for KHP acid (volume, mass/100mL, MM) so organising this makes stuff easier. 2. Learn the conversion between m/100mL and n/V (molar concentration). i.e. recall that with n=m/MM, we can make m the subject so m=nMM...

This theoretically is false, as the second stage of H2SO4 ionisation is incomplete (HSO4 is a weak acid that partially ionises), BUT needs to be assumed to be complete in order to be able to solve the question. Eagle Mum is completely correct in the context of the question, just a thought to...

I know that med schools have alternate rural and indigenous pathways but I've also heard from my tutors that some universities have a bias when choosing applicants for medical school - i.e. choosing fewer asians/indians (perhaps maintaining a quota of other backgrounds hispanic, anglo-australian...

prove\ that\ the\ max\ value\ of\ |e^{i\theta}-2|+|e^{i\theta}+2|\ is\ 2\sqrt{5} How would you solve this? Apparently there are methods using geometrical graphing or using trig algebra - feel free to solve outside these methods tho. Much thanks! :D

I empathise with you completely, I had (and am still battling) terrible procrastination from the start of high school, and was especially a problem as I had extremely high goals and expectations for myself and my family. I tried to limit computer procrastination with the carrot approach, with...

~Much Appreciated!

Is there a technique that means opening line for "Maman died today." (The Stranger CAMUS)? Other macro/medial/micro techniques appreciated for quote thanks1
