I have a question from the 2002 maths ext2 paper. It's Q6b)iii). Here's a link to the question: 4u 2002 exam Thanks guys, i'd appreciate any help. EDIT: GOT IT OUT! DOESN'T MATTER NOW...

Ugh...yeah I forgot about that thing called formula sheet. Thanks a lot guys! BCD

Hey, can somebody please help me with this question: Two long parallel conductors carry equal currents in opposite directions. The force between them is 3F. The current in one of the conductors is doubled, but the current in the other is reduced to a third of its original value. The...

Thank you!

Hey, can anybody please help me with an Integration question. Its from the Cambridge book, diagnostic test, p175 Here it is: a) Show that [integral of f(X) with limits a and 0] = [int of f(a-x) with limits a to 0] This bit is fine. b) Hence show that: { Int of [ (cosX) / (cosX...

Ugh! Can't believe I missed that. Thanks Mill.

Can somebody look at my solution for this question and point out where I'm going wrong? The answer is [(square root of 5) - 1 ] Q: find integral of: X / {sq root(1 + X^2)} My solution: let u =X^2 du=2X dx at X=2, u=4 and at X=0, u=0 Therefore integral becomes (with limits 4...

What's a "POM syllabus"?

Also you might wanna try: http://www.hsc.csu.edu.au/chemistry/index.htm I used it as pretty much my main source of notes. Or if you got textbooks, they'de probably be helpful too. BCD

*Identify the industrial source of ethene from the catalytic cracking of some of the fractions from the refining of petroleum. To what extent do we need to identify the process of catalytic cracking? BCD!

Actually Q5(b) out of the 1997 paper did not really ask us to derive the binomial theorem. It was mainly just testing algebra. And thanks lucifel for that bit of information. Cheers, BCD

Thanks Hayleekate!

Hey, Do we really need to know how to derive the Binomial Theorem? Thx

kami and dreamerish, thanks a lot for that! really appreciate it. Sol, i think they normally ask for two related texts for this topic and this should be sufficient for a band 5/6 answer. If you use too many, your answer may run the risk of not having enough detail. Anybody, correct me if i'm...

QUICK QUESTION: How important are related texts? Hey, Can anybody tell me how much information is required when writing about the supplemetary texts. Like in Journeys, they expect you to write the same amount for each text...what about powerplay? Thx
