Re: 2012 HSC MX2 Marathon question is in patel and terry lee

Re: 2012 HSC MX1 Marathon if the question adds otherwise then you are free to do it any other method, but keep in mind it is still 3 unit so the question is designed to be done in 3u ways and is most likely easier that way.

I'm on my iPhone ATM, but question 3 should be Done using sum of rectangles under curve and using The bigger and lower rectangles to bound it. I'll show You later if someone else doesn't But if you had to do it using induction it is easiest to separate the inequality and do induction twice and...

You can either use division of ordinates, which Is more obvious or multiplication of ordinates. For ln x/ x^2 draw each of those graphs for the pos X only as ln x doesn't exist in 2 or 3 quad. You should be careful when draw them both and note that x^2 Should always be on top of ln x...

This post is about the year 11 accelerated Maths class that is starting next Friday the 10th 5.30-7.30 at The Brain in hurstville. The class is designed for students who intend to do extension 2 Maths in year 12 only. The class will be high pace and most of the year 11 and 12 extension course...

if parametric eqns involve trig functions, i.e x=cost y = sint or different forms i.e. x=acost + b y=csint + d then what you will go in general is always try and make the sint and cost the subject in each subject. Then you will square both sides because when you want to eliminate trig function...

for an exam: given that |z|=|w| by vector addition a rhombus will be formed (here you draw a diagram including both z+w and z-w) therefore, the angle between diagonals is 90 degrees. i.e. arg[(z+w)/(z-w)]= 90 degrees (using angle between two vectors) hence, (z+w)/(z-w) is purely imaginary...

circle geo ftw!!! but yeh its place in 4u should be questioned

Even though harder 3u is my fav topic in 4u it should go...it is basically just harder applications of the 3unit course with slight variations. This to me seems like the board was too ceebs to make another whole topic, which imo they should. Either introduce statistics instead or matrices or...

Just ring up and enquire about the year 11 accelerated class on Fridays at 5.30

For the first part: We have 3 E's and 4 B's in total, i.e 7 letters, so they can be rearranged 7! ways, however since there are 3 E's and 4B's we divide by (3!)(4!) to cancel the repetition. so total ways = (7!)/(3!4!)=5040/(6x24)=35 For the second part we want to pick only 6 letters, now we...

In pokka's method a faster way would be from line two and:

well i think victoria's syllabus has got it right, they have vectors matrices stats and some others i cant remember. I think 4u kids should learn vectors properly so they can do the complex number vectors properly and also are able to better resolve forces in circular motion. However, if you...

Which do I pick? a) pure b) applied I pick mysterious option c) stats :p But I equally love all 3, each having their pros and "cons"

Stats/applied double major for me

nah stats is the third maths field which i will be majoring in with financial maths...and yeh i was gone for like a week or so but i was checking the forums from every so often, however nothing really exciting to do till this thread.

vs Stats?? dont leave poor stats by itself :(

I thought linear algebra adv 1902 was fairly easy last yr cause dave was such a good lecturer compared to santa in 1901...the only reason 1902 was hard was cause of the sem test...that was fairly hard...IMO order from easy to hard is : Math1905>Math 1903>Math1902>Math1901 but they were all...

Yeh de's in general, but I also love chi square distributions, there applications like determining whether data follows binomial model or symmetry between data etc suits me, also don't forget Taylor series

Yeh but lots of kids would of accelerated and learnt a lot more of the course
