I think it's correct. If you convert 1 - i and 1 + i to Euler form, you will find that 1 - i has an argument of -pi/4 and 1 + i has an argument of pi/4. Both have a mod of sqrt(2). We want the real part, meaning Im(z) = 0. The only way this can be done is if you have multiples of 4, since if...

I'd say just push through. Bad marks on tests do happen, as after all we are not perfect and are prone to errors. I can understand that you may feel frustrated by this mark - Perms and Combs is no easy topic and I struggled with it myself. However, it's only your first term of Year 12. There...

I would check on the UNSW website of what is expected for you as an international student. That being said, I have looked at a couple of degrees on the website now and UNSW seems to have not properly elaborated on NZ conversions to ATAR (see picture). Judging from this, I would say your best of...

Hey, I am in a similar position to you, though I never finished school. I have a Cert IV in Accounting and Bookkeeping so I am currently on the search for jobs as well while I am doing an accounts internship currently. If you want to go through the bookkeeping route, my first recommendation is...

Good luck everyone. Hope y’all do well.

Yeah sure I’ll come - just depends on location tho.

It doesn’t refresh if you come on the website via a notification

I think because people can select multiple answers maybe…?

Yeah, but that’s only because the parent function (arctan x) has a domain of all real x. If it was a function like arccos x with a domain between -1 and 1 inclusive, I think there would be those restrictions which you’d have to consider.

Recall that the domain of arctan x is all real x. However, for this question you have a restriction, that is the domain of sqrt(x^2 - 1). For the function y = sqrt(x^2 - 1), the domain is that x >= 1, or x <= -1. Since the domain of arctan x is all real x, the domain of sqrt(x^2 - 1) is the...

It's Latex. Personally I don't know how to use it yet but there is an option on the toolbar in the text box, denoted by "f(x)".

Yeah that’ll be a problem… hopefully it’s not too far away and something a bit more central within Sydney.

Done : )

Hamza made a really informative video today which is very business-oriented towards generating money through different ways of marketing. Idk if you have seen it yet, but I plan to do something similar through starting a YouTube channel. Personally I like Maths a lot and whilst I left school...

I’m getting Hamza vibes from this

Maybe do some sort of a poll?

Yeah I can understand social media as a way of slowing any progress of self-improvement. Personally, I feel as if I can deal with situations much better than I could say a year ago. The weeks before trials (which was about when I left school) was definitely a stressful period for me, and when...

Idk man, I was just in a weird mental state. I think when I said I was going to leave BOS forever, I was internalising all of the stress I had at the time and did a bunch of things which, under normal circumstances, I would have dealt with appropriately. Honestly though I can’t leave this forum...

Love your motivation to push through with your exercise! Hope you don't burn yourself out too much - I'd aspire to be able to exercise as much as you do.

Hope there’s room for old farts (2021 cohort :p), would be down
