hopefully we get a trig identities 'prove that' question. i'm good at them. although in saying that i've probably jinxed myself...
good luck!

such as volume of solids of revolutions, cartesian equation of a position vector, and implicit differentiation...
Will it be more likely to appear again because these are the types of questions they want to test in exam 1?
Or will it be less likely to appear again as they have already been in the exam the previous 2 years?
And awwww, i hope you'll go ok tomorrow Navman.
Your definitely better off than me :P I only learnt half the course lol.

Hmm, do you think that if a topic has appeared in both of the last two years...

i think they will come again just with a different twist to them

ZOMG!!! I HOPE THEY PUT ALL 3!!!
I LOVE THAT STUFF!!
implicit, solids of rev and turn to cartesian :smitten:

Haha me too, they're like the ONLY things i can do lolz :P
But yeah, i'm just worried coz they've used it the last 2 years they wont put it on the exam again :(

you confident with implicit now? thats great to hear! ... i probably didnt help, but hinder you ^^
would complex and vectors definitly be on? like if they put r(t) [vector type questions...( diff and antidiff. ) ] would their be heaps on other vector stuff?
naww now im not so confident...
Post by: dusty_girl1144 on November 02, 2008, 08:30:21 pm
Theres prolly gonna be a slightly hard trig integration question maybe likeor something similar as i havnt seen them test that before
dont u just let u = one of then... and one is the derivative and then go fourth?
or break up the sin bit or something? ...

Hmm, not that confident with implicit, but i like solids of rev coz thats just purely following a simple formula and cartesian seems easy. I can sorta do complex numbers a bit now too i think...hmmm
I'm so gonna cry if its gonna be all different stuff this year coz i haven't studied for them...i'll probs get under 10 :P rofl

they will most likely twist questions that are similar to last year... thats my wild guess
adding on....
watch out for "the" antiderivative and "an" antiderivative..
can lose u a mark

but i do think it will be on it... last year slope field was not done well, with "quite a few students had no idea how to tackle [the question]... they did not know what a slope field was."
Post by: trinon on November 02, 2008, 09:31:50 pm
Would you lose marks if you dont draw a table for the slope field cause i usually just do that in my head...However i dont think it will be on it this time, just a feeling..
Read my post again. Write down the table! It is needed and even if they don't mark on it (which I think they will), it'll provide a clearer understanding of the slope of the line that you need to draw. Don't be lazy because you can do it in your head. If I did that with the exam tomorrow, I'd lose 50% of the marks.

i didnt really get it coz we skimmed through it coz we were tight on schedual :(

This is what I mean...
Edit: fixed...
but then what do u do with that table? like how do u determine what gradient the line is at and stuff?
like everyone knows its a paraobla??
but get my question?

There's probably going to be a "Sketch the graph of y=[insert inverse/reciprocal circular function]" question
i was thinking that to just a few moments ago. because its never a question done really well!
and its been on heaps of the past exams too!
so im pretty well prepared for that q now :)

sweet id love that to be on the exam
lol yeah. I wish there will be alot of calc [like the previous trig integral q that fredrick gave]. I seriously suck at complex relations and kinematics :(
Read the assessment report for 2007:
Quote from: those vcaa bitches fk kents
Areas of weakness included:
• poor algebraic skills. This was evident in several questions, and the inability to simplify expressions often
prevented students from completing a question
• showing a given result, which was required in Question 2a. The onus is on students to include sufficient
correct and relevant working to convince the assessors that they do know how to derive the result. Just as
importantly, students should be reminded that they can use a given value in the remaining part(s) of the
question, whether or not they were able to derive it
• recognising the need to use the chain rule when differentiating implicitly (Question 3)
• recognising the need to use the product rule when differentiating (Question 3)
• recognising the method of integration required (Questions 4 and 8b.)
• recognising the need for an arbitrary constant when integrating (Questions 6a., 7b. and 8b.)
• recognising the need to use a double angle formula (Question 10a.)
• knowing the exact values for circular functions (Questions 1, 6a. and 8b.)
• giving answers in the required form (Questions 1, 5b., 7a., 7b. and 9).
and check the questions that most of the state got wrong [eg. euler and the 2nd last q]. :)
