Oh my bad

Microsoft as in microsoft office? Yea i have it downloaded on my mac. Microsoft office works for macs, in fact you can even get the free educational version from the microsoft website with your education email: https://www.microsoft.com/en-au/education/products/office Now if you are talking...

Sounds like you are going through a lot at the moment ☹. You should definitely take some of the holidays off for yourself to rest up and recuperate. Sounds like you are just burnt out from everything (can relate soooo hard) and that your expectations weren't met and that was a hard fall. I've...

Oh my bad. I did the proof by brute expansion on both sides but I felt like there had to be an easier way? Like is the only method for showing the LHS =RHS through expanding both sides cas I really can't see it being done any other way, but then that seems to tedious

I expanded it already, but like isn't there an easier way than brute expanding it because usually idk with some algebra manipulation I can show that they are equal without expanding it???

So usually for mathematical induction after you assume true for any integer k, and then you try and prove for k+1, and sub in the RHS, it's some easy algebra manipulation and they end up being equal. I don't know why but I've been staring at this question for 20 minutes and I can't seem to be...

Usually people don't go tutoring for biology as it is predominately content (the same reason why people wouldnt go tutoring for geography, economics or legal). Your school might offer edrolo (basically an online tutoring service, teachers go through syllabus points and there are notes and topic...

Oh gosh 2 extension subjects seems like a lot. Normally most people with 12 units have 6 assessment tasks, but as you do 2 units of ext subjects you have 7. As you do 12 units you already have less time to allocate on each subjects than those that do 10 units. It seems like music extension is a...

I tried that but I got the same answer? Maybe it's something wrong with my algebra? I get LHS = 1/z + 1/(conjugate of z) = z+ conjugate of z/ (mod of z squared) = 2 Re(z) /r^2 = 2rcosx / r^2 = 2cosx/r ????

I don't know why but I keep doing this question but I keep getting the same wrong answer. The question is: Using Euler's formula, e^(ix) = cosx + isinx, show that if z=re^(ix), then: 1/z +1/(conjugate of z) = 2cosx/r^2 For some reason, I keep getting LHS = 2cosx/r instead of 2cosx/r^2

I did bio, chem, eco and phys in year 11. Bio is quite content heavy and chem is a mix of content and concepts. If you are organized and you don't fall behind in the workload (hmw, assignments, etc) you should be fine.

The 4unit calculator can also do some other stuff like vectors, and other things that arent on the normal 82AU calculator. I mean 4unit calculators are pretty basic when it comes to simplifying complex numbers but having the 4unit calculator means you are able to check your answers. Ultimately...

I hope they help :)

I did animal farm in year 8 and I have some resources + the essay I did. Would you like it?

I can! But I don't get home until 8pm. So the earliest I can send it is 8pm
