Andrew's Guide to IB Mathematics Universe

This is it, ladies and gentlemen. The last section in the trig quartet. After brushing it off for 4? 5? months, I've finally sit down and finished this unit. It's quite a lot of work writing these booklets, so I'd really appreciate if y'all could buy me a coffee here and there. Every journey has to come to an end, and I'm sad that this is all the trigonometry that IB has to offer. But hey, further down the line you'll learn more  ways to prove trig identities (wink wink: complex numbers), which only emphasise the importance of knowing your trig well.  Enjoy!  P/S: I'll take a short break, maybe a month or two, cause I'll be travelling. Promise that after the break my brain will be free of clutter - I took a brief break (couple days or so) not writing questions and I'm blown away by my eagerness to come back to it. Be nice to yourself, your friends and your loved ones. Your favourite wolf will be back in August/September! Credits:   AdventurousAndrew#

Hi. Yes. Another month or two flew by before I could release this last bit of topic 1 - complex numbers. As mentioned in the document, I didn't include simple examples because y'all should be able to do them by the time you read this document. Don't be shocked that I didn't start with "adding complex numbers in Cartesian form". There are certainly one or two questions like that in the practice section if you do need a brief recap. Unsurprisingly these booklets take a WHILE to write, so I don't think I can finish the entire course this year. Will try to chuck out topic 2 and 5 though, alongside the mocks and the spreadsheet of topics I mentioned last time. Enjoy the summer, everyone not in Aus/NZ! :D I'll see y'all again soon! c: Andrew

Hey there cuties. For many of you, summer's right around the corner, and I'm sure some of you are looking for more questions to do before your end-of-year exams or to prepare for DP2. You're at the right place - I'll give y'all a collection of resources that will be useful for your preparation. IB-specific resources 1. Christos Nikolaidis's website:   IBDP homepage . He has more resources for AA students, but AI folks would also find some of them useful. I recommend taking a look at his topic tests. I'm not a biggest fan of his lecture notes to be honest, but if they work for you, by all means, go for it. The exercises are pretty routine and predictable. I'd say they're representative of the real exam, but in my opinion , they're a little boring and you need to learn to be able to solve these questions without such scaffolding on D-day. 2.
