1. ### Need a practice test based on mathematical induction and trig. equations 3U

I posted the solutions on another thread a while ago. One sec, I will try to find it Edit - bottom of this thread https://boredofstudies.org/threads/maths-practice-papers-new-syllabus.389146/page-2#post-7321108
2. ### help with problem solving

Could be, I haven't thought about it too hard, but generally with questions like this a recurrence relation is the way to go. I haven't done anything like olympiad tutoring or much olympiad maths in general though so maybe there's a nicer way to do them with combinations.
3. ### help with problem solving

Here is a diagram that will hopefully help with the explanation for b)
4. ### help with problem solving

This is not the answer I get, and I don't see how combinatorial techniques could help with this question, but feel free to explain how you've done it. I have come up with a nice solution for b). Let f_n denote the number of ways of filling a 3×2n rectangle. First of all, consider the 3×0...
5. ### help with problem solving

Yeah you are right, edited original post.
6. ### help with problem solving

With the first one, you are given that 3 of the sides are perpendicular, so obviously the solid is a section of a rectangular prism. Now each face of these 3 perpendicular sides is a triangle, i.e. half of a rectangle, meaning you effectively have (1/2)*(1/3)=1/6of a rectangular prism. Also...
7. ### Do you want to go to a US or UK University?

Ah ok, thanks for the clarification
8. ### Do you want to go to a US or UK University?

What are the Go8 universities? I'm either going to be going to ANU or USyd for maths and I heard they both are internationally recognised. I won't be able to afford to do undergrad at an Ivy league uni though and I also have no olymiad experience so as silly as it is I would have no chance...
9. ### Maths/Science @ USyd Vs Maths/Science at ANU

I got my results back and did better than expected, getting guaranteed entry into USyd BSci/MMathSci, supposedly with Daylell Scholars, but I don't know if this is better than the Mathematical Sciences/Science degree at ANU. In terms of location, I would have to move away from home for both unis...
10. ### Do you want to go to a US or UK University?

I cannot afford a foreign undergrad degree, but just wondering, how difficult is it to get into a well ranked US university for a pHD/graduate program, coming from an Australian university? I am considering the possibility of pursuing a pHD in maths, if my uni marks are good enough.
11. ### Maths @ USYD vs Actuarial+Applied Finance @ Macquarie?

Ok nvm, found the email about that lol. I'd assume that means we are eligible, it says on the website 98+ and a Daylell eligible course.
12. ### Maths @ USYD vs Actuarial+Applied Finance @ Macquarie?

I can't really answer your question sorry, but just wondering, did they already offer the Dayllel Scholars Program to you? I preferenced the BSci/MMathSc at syd and got a 98+ atar but they haven't said anything about it to me yet.
13. ### Has anyone done this and is it possible?

If I were you I would definitely do it. Self learning the maths courses is possibly the best way to get a solid understanding on the content, since you are learning at your own pace, and doing it fast allows for more time to actually practice the content, which is how you do well in advanced...
14. ### HSC 2019 NSW School Ranking

A bit of a different topic, but the work environments at all those top schools sound horrible, specifically the selective schools. Doing 10+ hours of tutoring a week would completely kill any social life you may have, as well as the ridiculous testing conditions some have. I'm glad to have...
15. ### HSC 2019 NSW School Ranking

This is why the system for school ranking should be changed. It can be so easily abused like this with just percentage of b6s. Imo the factor should be median atar
