I doubt it. Difficult real world related rates questions (that stay within the scope of the syllabus) don't really exist. Trebla can vouch for this.

exposure to all of elementary mathematics will help but there are only so many hours in a human lifetime.

general expansion question xd idk

they've finally run out of idea so they just pulled a giant expansion question

Question 16 is a meme.

4U should be out tonight

No. The case 0<b<1 can be transformed via a functional equation into the valid domain over where the result was proven to be true. Perhaps you should keep staring at the paper.

The number of cards on the nth turn is n+2.

what do you mean? you just replace n with k, they're just variables.

I believe the correct question would be did anyone have a q16 to hand in at all. And we had less than half of them attempted.

why everyone skip q16 ;_;

The toilet of the second floor is comparable to USYD Carslaw

We are aware of train delays, or own crew is affected by this, so you will not miss out on the start, please don’t be a no show

Re: HSC 2018 MX2 Integration Marathon The above question is literally impossible, in the sense there is no elementary closed form in terms of a finite combination of elementary operations and HSC-level constants.

whoosh was a joke my dude

It really isn't. Tolerating intolerance is never the answer.

For all positive real numbers, the iteration derived from Newton's Method applied to the equation q(x)=x²-2 results in the f(x) described above, and converges to the positive real root of the equation. Hence, fn(x) converges to √ ̅2 for x>0 The point x=0 can be discarded, as it is a set of...

slight overkill you can just use the thing i just posted with a riemann approximation to find the limit

The first and last index terms can be discarded, since log(1) = 0 Rearrange the factorials to obtain: \lim_{n \to \infty} \frac{1}{n^2} \sum_{k=1}^{n-1} \log{\binom{n}{k}} = \lim_{n \to \infty} \frac{1}{n^2} \sum_{k=1}^{n} \log{ \left( k^{2k-n-1} \right) } From there, an integral...
