yeah I think that's the one I did too I think

I wrote 1) sensitive and private, linking to the Medibank leak that exposed abortion data 2) it could be overwritten, leading to poor medical diagnoses that results in poor treatment

Our teachers sets Edrolo and Atomi work. Edrolo topic tests are nice imo, videos for both are boring. Imo Edrolo questions > Atomi questions mainly because of Atomi's poor UX.

Ye, I should've clarified that - if they give you a u sub you have to use it. Thanks for picking up on that

You don't need to use u sub to integrate sin(theta)cos(theta)^2. The first on the formula sheet for integral calculus is when f'(x) (-sinx) is next to f(x) (cosx) to the power of n (2). In fact, they didn't even need to give you the u sub. [Edit: if they didn't give you the u sub] you could've...

Isn't it \pm\frac{1}{e} because \int\frac{f'(x)}{f(x)}dx is ln|f(x)| + C not ln(f(x)+C?

I think that sigma notation is extension 2 now. Nesa writes " Sigma notation is formally introduced in the Mathematics Extension 2 course in the topic MEX-P2: Further Proof by Mathematical Induction. ". You need to still be able to do this question though - I recognize it from a yearly paper I...

That way is very clever. Just for comparison, I will post the solutions to the Baulkham Hills paper I quoted it from. Took me 10 minutes with the wrong solution when I tried to do the question half an hour ago after warming myself up with easier binomial expansion questions

When looking at the HSC past questions and Baulkham Hill's 2020 year 11 ext yearly the types of ways the question can be asked are: 1. constant term 2. coefficient of specific index 3. coefficient of x^3 in (1 + x + x^2)^5 4. I don't even know how to summarise the next question.

Does anyone know where good past papers are for science specifically the Valid examination or have general tips? Thank you.
