Hello :) I have a speech on Belonging coming up for which there is no specific question -- I am only asked to "present my view of 'Belonging' through an explanation of my prescribed text and its relationship to related texts." Now, I'm having trouble getting a thesis/intro up. I guess that...

From Patel 1B, question 2(f): |y|=|x|+1 I tried it a few times, got a few graphs up, however none of them looked like the answer. Patel's answer matches up with Wolfram Alpha's, so it can't be wrong lol. Could anyone guide me through the steps to get the resultant graph? Thanks :o

Awesome...so the question now is: just how many questions are exactly the same as those in the original Patel? And just as importantly, do exercises and the ordering of the matching questions within those exercises correspond? (it would be a pain trying to find the worked solution to your...

lol this has me confused :S Izzy's description of combined is the same as iRuler's description of double degrees. So ajdlinux is correct...I hope

Anyone know how I might put on of these widgets on my desktop? Mine starts 15th October btw :) I have made a timer on Widgetbox but it gives me a code to copy and "embed" -- not sure what to do with it?

My 4U class uses Patel, and it's quite an old version as far as I can see. It doesn't have worked solutions, and I can't seem to find any on the web. However, I've heard that the "Excel" version of this book has worked solutions. Is this it? EXCEL HSC - Maths Extension 2 Year 12 Does it...

What would one say about validity? And how to improve it? I was thinking: --> soot formed at bottom of can shows that combustion is incomplete. Since the aim is to find molar heat of combustion, which by definition requires complete combustion --> INVALID? To improve validity to this effect...

Thankyou on both counts! :)

1) I got your answer, and by your same reasoning as well. So maybe the Fitzpatrick answer is wrong? 2) I'm not sure about your answer for this. Fitzpatrick's answer involves some manipulation as a result of x being in degrees. Besides, it's the last question of the exercise, it can't be as easy...

After going through the first 2 dotpoints (starting to summarise, finally) I've had trouble with a few things. Any help would be appreciated :) 1) If butane were cracked down to ethane + ethene, ie. C4H10 --> C2H6 + C2H4, how would these 2 products be separated? My Excel textbook has a diagram...

So I got everything in the exercise right, except for the last 2 questions, as below: Find the derivatives of: Q44) tan(pi - x) Provided Answer: -[sec(x)]^2 Q45) tanx` Provided Answer: (pi/180)[sec(x')]^ I'd appreciate if someone could explain you get to these solutions. Thanks :) Note: -...

Re: Chemistry HSC questions sorted topic-by-topic Thanks again for your help and the quick reply :)

Re: Chemistry HSC questions sorted topic-by-topic Thanks, will check for those too. You wouldn't know if there are any such topic-by-topic sortings for Math/MX1/MX2?

Re: Chemistry HSC questions sorted topic-by-topic Mmm, I figured as much. But the Success One books do have fully worked solutions to these, right? If so, I can just get down to the library...

Re: Chemistry HSC questions sorted topic-by-topic Wow! Thankyou so much :D Where would we find the solutions to these? I've heard the SUCCESS ONE textbooks have worked solutions? Any free resources though?

Thanks everyone for your replies! I've downloaded Ahmad Shah Idil's notes, from my short browse they look fantastic, I'll just have to format them to look less intimidating! Props to him :D -- Are there any further notes anyone would recommend from the downloads section? Looks to be exactly...

Thanks js :)

Awww bummer, thanks for notifying.

True, I will get to a shop when I can....atm studying for other course exams, thankfully not Chem lol :mad1: Anymore opinions? I tried d'ling the preview of the Chapter 1 of Jacaranda, I signed up but it still wouldn't give me my download. Odd.

Haha damn, don't really wanna purchase the two of them...moreso going for a single, ultimate source (I'm terribly unorganised. More textbooks = more mess and bother) Thanks and luck to you too
