Hello, my name is Scott. I'm offering tutoring for Maths Adv, Maths Ext-1 and Physics. My ATAR was 98.55 and marks are as below: Ext-1: 95 Ext-2: 91 Physics: 90 I'm currently studying Space Engineering at University of Sydney, I also received a high distinction (85+) for both of my maths...

When considering a subject you choose, I would say picking it based on: your performance ≥ your interest > difficulties of the subject for you > scaling I think typically a band 6 give a boost to atar regardless of the scaling, so I suggest you to check the honour roll online about the amount...

In the calculation of the velocity or potential energy of LEO and geostationary satellite, with v = √GM/r or U = -GMm/r, many textbook solutions only consider the amplitude of the satellite as r, instead of the sum of Earth orbit and the amplitude. Is this considered as an acceptable solution in...

Thanks

The diagram below is a roller coaster track, the person riding the rollercoaster is feeling their weight increase and decrease at different points. Which point, A or B is the apparent weight of the rider at the greatest? I choose B but the answer choose A, the reason for the A in the answer...

nvm, I didn't realise this was a question about prove by induction

question 6

I may try to do other questions later, but these questions need to take a super long time so I can't do it altogether. (definitely not just reluctant to do probabilities lol). If you have a question on question 4, feel free to ask.

This is some very messy stuff but it is the solution to question 4.

In the new syllabus, most of the content in complex numbers, integration and mechanics are the same as the old syllabus, but proof and vector are completely new topics.

okay sorry for the trouble then

If it's copyrighted, then can I post a request for the source to buy the textbook solution? I couldn't really find it

thank you

I posted a thread about Cambridge Maths Extension 2 textbook yesterday, asking if anyone has the worked solution for that textbook, and the thread was gone, deleted on the second day which is today. I receive no notification or any reason why it was deleted. If people going to delete a thread...

You cannot, did you or the question itself defined the variable p before? like p is an integer or something? If you didn't then define it, if you did, you can either define p+1 as P, where P is also an integer (or whatever you defined it as), you can also use := sign, which means something is...

most importantly, what is your rank in your cohort?

its scalar but can be both positive and negative, because its derived from integration I think, which can be negative

As the question, how can I know if the magnetic flux is a positive value or a negative value? I searched that positive flux leaves a closed surface, and negative flux enters a closed surface. If this the case, does this mean the flux below an area would be different from the flux above an area?

In my personal experience cheat sheet for maths are practically useless, unless some values like tan 60°= √3 you couldn't remember, or something that can be a bit confusing at the beginning like the conversion of the radians, you can write them down. Some other notes such as the approach for...
