What ARNT You To Sure About For Tomorrow? (1 Viewer)

[DeanM]

ahhh okay i see, thank heaps! 100% here i come.. (not really)

 

[taco man]

can somebody help me out here, im not sure about recurring decimals, eg: for 0.135 where the 1 and 5 are repeaters would the whole thing go 0.135105105... or 0.135151515...

 

[roadcone]

if there is a dot above the 1 and the 5 it is ... 0.135135135...

 

[taco man]

o okay thanks

 

[Sonic]

o okay thanks

ahhhh......
i'll leah q 10 out of the way and i sould be sweet but that's only 90% if i ace everything...
oh well that's prob what i was gonna get

 

[Kutay]

thats one i havent heard for awhile... (2n-4)*90 (sum of interior angles or an n sided shape)

Hey DeanM the rule for interior angles is (n-2) * 180!!!

Should memorise that one as easier i believe

 

[scoby_2000]

remember:-

1. "ratio of intercepts on transversals passing parallel lines are equal"

2. volume of cone = 1/3 pi r² h

3. add interest before subtracting the monthly/yearly payment in loan repayments

4. similar triangles are your friends

5. know your graphs of secx cotx and cosecx or how to work them out at least

this was really important in the 99 and 00 paper...thought it was wierd...i had no idea wat transversals were...but i know the better now

 

[DeanM]

im happy to say i now know how to do loan repayments/anything with money.. phew.. except for that one in the 2001 paper... that was just CRAZY

 

[mcs]

i hate loan repayment questions- i can do compound interest and superannuation stuff without a prob but I always stuff the loan repayment rubbish up!

 

[chin music]

Ive studied like a bitch and tried to completely understand loan repyayments but i just cant get them. Ill prob get it if its a straight forward one but a really hard loan repayment one will get past me (eg the 2000 one) i wouldnt get that for my life. A hard probability one also scares me. I hate it wen u get marked on ur tree or whatever diagram coz thats not how i work it out.

 

[jemsta]

remember.....do not leave anything blank
make sure you attempt every question possible!!

 

[DeanM]

does anyone know if we are allowed to use pencil ?? cause on all the tests it tell us to use 'black or blue pen' .. but teachers at my school have always stressed to use pencil when drawing a diagram.. does anyone know ?

 

[jemsta]

yes its an abolsute must
pencils in diagram while all your working out and answers have to be in pen

 

[PoP 'n' Fresh]

you can draw diagrams in pen. No biggie. just that if you make a mistake somewhere towards the end it gets messy.

I find Geometry + Trig combo-ed questions are tough...
Probability is ok, some of the series questions are sketchy, but the worst one is:
The quadratic polynomial + the parabola!

y² = 4ax
(x - h)² + (y - k)² = r² etc etc *shudders at the word latus rectum*

 

[Tulipa]

O_O

i know nothing

i do not know any calc stuff i swear
am fucked for most volume about the y and x axis stuff

but i can do geometry! and most trig! and series and sequences! and probability!

that not knowing calculus is going to screw me up isn't it

jus do what u can tonight
differentiation/integration will be appearing at normally question 3.....almost 1/4 of the marks are calculus based i think

i have been

its just the basic stuff is fine with me, but when it gets complicated i get scared.

oh and the whole compound interest questions and all that? *shudder*

im horrifically bad at math though, if i get higher than a 60 for the whole course i will be ecstatic

 

[jemsta]

do not get scared
do not let the fukin exam put you down...u have to overpower it
if u have confidence ull do fine
i need to have more confidence...ill fukin suicide if i dont get a band 6 for this shit

 

[Ghost1788]

I'm confused between the stuff I have to know for 2U and what I have to know for 3U...

anyone willing to list the major difference in formulas....



as for logs its easy

abc - bac
log_a b=c
b=a^c

change of base

log_{old base} x = ln x/ln oldbase
