If I drop another subject I'll be having a free period a day. I got an actual goated timetable lol.

I'm a 4u student and my fav levels of math (ranked) are 3U then 4U then 2U. But 2u is so chill it may as well be 7 free periods a fortnight lol.

Imagine grinding for the hsc and then u get a headache/stomachache in the final exam lol.

Memorise? I'll be honest, I remember basically everything on the formula sheet, but never product-to-sums. Just remember the sheet is always there for your reference

The 'degree' of a factor is called its' multiplicity A root of multiplicity one just passes through the x-intercept A root of multiplicity 2 has a tangent to the x-axis at that point, for example x=-1 and x=3 on your graph A root of multiplicity 3 has a point of inflection to the x-axis at that...

@Masaken Answer cannot be D because the way of arranging 9 people with no restriction is 8! < 86400

You can't be serious. You've already studied 12 modules of science in 6 weeks? I'd take it a bit easy but ensure that you get enough revision throughout the year.

Yep even I had a 30% task (multimodal). Absolutely demotivating when u get a terrible ranking in that.

Lol its looking like everyone (myself included) fails their first english task. At our school the first term's multimodal weighting > Trial weighting so it's a rocky road from here on out.

What school rank if I can ask? You can give a ballpark range if you don't want to say exactly.

Is this by percentage of maths students achieving Band 6? IIRC, this has happened in past years, because these schools force more of their students into 2U and away from 4U. I'm really skeptical these schools have more genuine maths skill than JR.

I'm planning on doing a Bachelor of Economics at USYD beginning in 2023, and since I can pick two majors, I was considering mathematics to be one of them. I've always been very good at math, and learn independently and take a natural interest in the subject. My main concern is that uni math...

sinx and cosx is negative. Therefore beta is in the 3rd quadrant and approx. 216.8699 (3.785 radians)

If i had to pick the most correct answer (that is only somewhat correct) I would say C. It does have modulus root(736) and each component (i,j,k) has been scaled into the opposite direction, even if they haven't all been scaled by the same factor.

I am wary of 'choosing a subject because it teaches discipline in another'. While it might seem like multiple essay subjects can help your improve writing, it could increase your workload a lot, and if you hate essay writing, you're going to especially resent picking them. In my opinion, I...

I really needed to hear this. I'm in an almost the same situation lol.

@President KK K and L surnames are both in there, under K section

This would explain the error I'm seeing. I think every person in the k category was actually a 2020 graduate.

I've found a person on the list that I know graduated in 2020. Surely there must be more errors like this.

8. Suppose the two factors are a, b > root(n) ab > n, which is a contradiction since ab = n as we define them as a pair of factors to n. 9. a) n^2 = 4m - 2 n^2 = 2(2m-1) The RHS is even, implying the LHS is even. For n^2 to be even, n is even. b) Let n=2p. 4p^2 + 4 = 2 2p^2 +2 = 1 2(p^2 +1) =...
