Are we allowed to use double sigma to find the coefficient in for example, (1+x)^2n = (1+x)^n (1+x)^n or do you have to expand it and evaluate by inspection?

Just remember that this is what year 12s in America are learning about Hint: the first one is 101 Dalmatians

'six or seven' schools evacuated including ' Willoughby Girls High, Castle Hill High, Thomas Reddall High, Mount Annan High, Elizabeth Macarthur High, Picnic Point High and Jamison High.' Apparently due to bomb threats in emails...

Relatively speaking, English was easy, and now Ancient History was easy. Do you think all exams will have been changed to become easier due to covid since it is pretty evident some have been changed? Also considering this is the first year for the new maths syllabuses, but for sciences being the...

"From HSC 2020, NESA will begin reporting HSC marks for Mathematics Standard and Mathematics Advanced on a common scale. This change was introduced by NESA in part to "[disincentivise] capable students who deliberately choose easier courses for a perceived ATAR advantage". This change means...

Which atar calculator is the most accurate, because entering the same marks in matrix, talent 100, atar notes, hscninja calculators gives quite a significant difference (matrix in particular is a lot lower than everything else).

If I wanted a external mark of 95+, what would be the raw mark required for that generally in each?

For motion questions and similar, can you use bounds to integrate or do you have to sub initial values? Also, can you put expressions into the 'd' instead of using substitutions in 3u?

Since it is the first degree in the world

Do they just add straight onto your atar cause that seems kinda broken

Hi, I currently have a very broad idea of what to apply for and i'm struggling to narrow it down. I originally wanted (but not a strong desire) to study medicine but my UCAT is too low. Would it be worth it to continue trying to get in if i'm not absolutely set on getting in? Also, how much does...

When bromine water is added to cyclohexene, why and under what conditions does bromocyclohexanol form in addition to dibromohexane? Also, when giving amounts to add for an alkene, alkane and bromine water what amounts should be given? e.g. for 5mL of cyclohexene is 3 drops of bromine water...

I'm worried my extracurricular life is poor as I basically dropped off from them around year 11, so how much will this impact my application?

Does anyone have a list of the 3U and 4U topics that are in the prelim and HSC course for 2020? Thanks

2001 Q18 c) describe and compare the vertical forces acting on A and B at their maximum heights. I worked out that for A, the force is gravitational force which is equal to mg = 294N. For B, I thought that the force acting on it would be gravitational and tension(??) both downwards which add to...

Q19 2007: Analyse Einstein's Theory of Special Relativity and the evidence supporting it as an application of this model of scientific method. What points do you have to talk about for this question? What i am thinking: -Einstein developed the Theory of Special Relativity from application of...

1) Explain the reaction of an amine and water in terms of Lewis and Bronsted/Lowry theories. Also, what are the general points you would talk about when asked to refer to Lewis and Bonsted/Lowry in organic chem? 2) How can you convert ethene to a secondary amid without hydration or alkane...

I was checking an atar calculator (talent 100) and is it true that you would need 95 in business studies to be equivalent to a 99+ atar? Are the marks entered the raw marks or scaled?

Outline the steps to convert 2-methylbutane to 2-methyl-2-butanol and name a test to confirm that the product is an alkanol. Using the equation for the reaction of 2-chloro-2-methylpentane with a strong base, will colour change will be observed when the product is mixed with acidified potassium...
