It's apparently two years later, not next year.rparjf022 said:I heard they're removing conics from the 4U syllabus from next year and replacing it with statistics.
Apparently they've wanted to remove it for some time...
Anyone else heard of it?
yeh but what about those kids who want to draw ellipses or hyperbolas at uni? How will statistics help them?midifile said:I actually dont mind conics once you get over trying to work our what the questions are asking.
I think statistics will be more relevant for students who want to do maths or actuarial studies in uni
Lol, just lol.cccclaire said:yeh but what about those kids who want to draw ellipses or hyperbolas at uni? How will statistics help them?
Statistics will only be studied in the 2U preliminary. for more info check out www.boardofstudies.nsw.edu.aurparjf022 said:I heard they're removing conics from the 4U syllabus from next year and replacing it with statistics.

no conics or circle geometry. damn i wish i was doing that new coursesicmacao said:Statistics will only be studied in the 2U preliminary. for more info check out www.boardofstudies.nsw.edu.au
For 4U, they removed conics and replaced by differential equations. Also they replaced harder 3unit topics by one topic (inequalility which means there will not be killer geometry questions in the future 4unit paper). Even more alarming is that geometry is completely removed from the 2U course while in the 3U course, students are still expected to learn circle geometry.
In the past in 2U level, students were asked to check
if y = sin x is a solution to
y'' + y = 0
Now in the new 4U, students have to find a solution to differential equation such as y'' + 4y' + 3y = 0. i.e. find f(x) such that y=f(x) satisfies y'' + 4y' + 3y = 0.
You may check that y=e^(-3x) is a solution to the above. Students will be taught techniques to solve these type of questions in the new 4U course.
In fact solving differential equations are not completely new in the NSW maths syllabus. In many 3U textbook in particular the fitzpatrick book), a proof is given for the solution to the differential equation y'= k(y-p).
Also in mechanics, many problems were in fact about solving first order differential equations.
holy cow, r u sure, farrrrrrrrrr out, im doing 4u maths dis year. i coulda done statistics instead.rparjf022 said:I heard they're removing conics from the 4U syllabus from next year and replacing it with statistics.

yes thats a good point... at least we have stacks of psat papers we can do + heaps of books, notes etcashik1 said:holy cow, r u sure, farrrrrrrrrr out, im doing 4u maths dis year. i coulda done statistics instead.
Well, at least one thing is 4 sure, all the 4u kids next yr are screwed cos when they do past exams, there wont be any 'statistics' questions and the 'conics' questions will be useless
Yeh, i will be starting 4U at the start of the 4th term next year, will i be affected?Exphate said:Are you doing them accelerated (ie this year?)
Statisics definitely get more complicated in the new 2Unit course. One of the topics taught is correlation and regression. Regression will be a very useful subject. It is known that 2 points determines a line. However what if there are 7 points on the coordinate plane but they don't lie on the same line. We find the line of best fit. Many data in real life needs to be model by line of best fit. This will allow us to make simple prediction about the future.ronnknee said:Wow then the syllabus is rigorously changed then...
Statistics in 2U, removal of geometry :|
I don't think I would enjoy statistics
It was pretty boring in Year 8 haha
Then again, my perception might change if it gets more complicated such as finding something different from the range/mode/mean
Differential equations sound interesting
line of best fit! We learn that stuff in year 8 science!sicmacao said:However what if there are 7 points on the coordinate plane but they don't lie on the same line. We find the line of best fit.
I think there's a little more to it than eyeing it off lolkurt.physics said:line of best fit! We learn that stuff in year 8 science!
