Thanks Drongoski.

Thank you Drongoski

I suppose your question is just about part (e) ?

Personally I remember the triangles, just like for t-results. Either picture it in mind or just draw it on paper if not sure. Otherwise for t-results, you have 3 fractions(=6 items) to remember. And for exact trig ratios, there are many more pieces of information than the two triangles...

I think people are talking about totally different things. I somewhat understand what you mean, but consider these scenarios: 1. you're a maths tutor and the student never does his/her homework. And he/she thinks "Numbers are SCARY !". 2. you're an English tutor and your student does not...

This might be a lengthy and "time-wasting" explanation, but I couldn't see any "short cut" way. It may take while to understand something, but once you do, it will save you much more time. It seems that you know the algebraic rule of differentiation (i.e. bring the index down and reduce its...

So what's your possible plans for university ? Would it require some degree of mathematics ? If yes, you're much better off tackling the problem earlier , rather than avoiding it and leaving it for later. (in most cases, problems never get solved that way) Just imagine cramming a two-year...

self contradictory ? Just a quick check: if you sum up the probabilities for m=0,1,2,....,n , shouldn't they add up to 1?

@OP,I think this is what people are talking about(Kudos to Carrot :D) :

found this discussion from a year ago: http://community.boredofstudies.org/18/physics/317312/less-maths-makes-hsc-physics-dumb.html

In terms of scaling, they are all quite good. So it's really up to you to decide what to drop. Also you could consult your teachers/head teachers/year advisor.

I don't think it's fair for us to comment on the difficulty of a course without knowing your strengths and weaknesses.

Did you mean dropping it this year or in Year 12? If it was for this year, you wouldn't have enough units (12 units are required for Year 11, only 10 units are needed for Year 12) If it's meant for Year 12, well , by then you should know whether or not you like the course content (probably the...

When you compute the probability for getting n A's and (n-m) B's, the next draw could be either from A or B. Say P =\frac{\binom{2n-m}{n}}{2^{2n-m}}, then for this case where we need an A on the next draw, we get \frac{P}{2} And similarly for the case where we find B empty , we get...

Consider the case where A and B both have 2 matches in them. So n=2. And we want to find the number of ways such that the box B has 1 left(i.e. m=1 ) when A is found to be empty. Then before we open A and find it's empty(taking a match for the (2n+1-m)= 4th time), we've drawn 2 matches from A...

As you said,"box A must have be drawn n times and box B be drawn (n-m) times" before we draw from box A again and realise it's empty. Then \binom{2n-m}{n} =\frac{(2n-m)!}{n! \times(n-m)!} is the number of ways you can arrange these (2n-m) items [ with n A's and (n-m) B's. ] It's like those...

A friend of mine actually completed his degree recently, and he's searching for ANY job (like just a generic engineering one) You have to be REALLY competitive to find a job in a relevant area, but I guess it applies to most degrees , just more so in Aero(space) because of the limited...

From what I've heard during the their presentation (for the aforementioned program) a few years back, it's VERY VERY rare for an Australian to make it into NASA Not sure about Korea though

well, for English, the amount of tutoring does not necessarily have a linear effect on improving assessment results because it hugely depends on the student's part (speaking from personal experience: I tried quite a few tutors/tutoring centres for English during my HSC and it didn't help much...
