thank you sooo much for that! it has cleared a lot of things up. However, just wondering how you got from line 1, to line 2. if anyone else is willing to help, you've already done a lot.

http://www.boardofstudies.nsw.edu.au/hsc_exams/hsc2003exams/pdf_doc/mathematics_03.pdf question 10 part ii) i just don't seem to get the right answer, probably because my differentiation has become quite a bit pitchy over the last year.

what would a raw mark of 80 equate too for 2 unit?

read it, read it, read it, then write it, write it, write it. Never fails.

thanks

^ have you been studying all week?

fair enough.

maybe if you guys did your work in the day, then you could sleep?

what if you open your own pharmacy?

having problems calculating ppm. e.g convert 0.93% (v/v) of Argon to mL/kL how would you do this, i normally solve these questions by using ratios so if you can do it that way it would be great. Also is mL/Kl the same as ppm? i though ppm was mg/L

Holy shit! You're pretty accurate with the subjects i do. except i don't do modern. if i got 50.60 there will be no more girlworld_club. Yeah, i'd probs die. I'm literally so depressed atm.

Thanks for posting it so others can see.

i'm currently at the pinnacle of procrastination. plus i can't study past 9, except 1 week before an exam. I'm so stuffed.

sleep. i know i will be deprived. Then depending on how depressed i am..i'll hit the choc bar or the flight centre.

i've done nothing. it might kick in by the end of the week.

i am also having problems with question 31 pg 224 of conquering chemistry hsc on sulfate experiment.

Exactly how much detail are you supposed to know about AAS for hsc chem. I had a look at conquering chemistry and the types of questions are on calculations which are difficult. However, i have yet to see a hsc exam with very difficult calculations involving AAS.

interested in peter skryznecki, pm me?

Also how do we integrate In2 ??? thanks

How does: 1. e^20k = 2 equal 20k = ln2 what is the working in between? 2. also what is e^x = 0 3. and another one, how would you solve e^x = 20 i.e what is x? 4. Also how to solve 2^x thank you so much for your time.
