Hi, I was trying to decide which course to choose between CHEM1011 and CHEM1031. Which course would you advise, considering that I got 88 in chemistry in the HSC and intend to do the GAMSAT? Also is CHEM1031 really hard, or is it doable with effort? Thanks

Hey, just wanted to know what im looking at for these ranks Chemistry: 2/27 Biology: 4/69 Business Studies: 3/49 Mathematic: 13/50 English Advanced: 34/68 Our cohort is really strong and competitive in math and english My school rank is in the 190's Thanks :)

Hey, im stuck on this question.. can anyone help ? Find the stationary point on the curve y=ln x/x and determine its nature. I get stuck after using the quotient rule and getting (1-lnx)/x^2 = 0 (for stationary point), can anyone tell me how to do it properly. Answer (e, 1/e) maximum...

Hi, I got stuck on this question Find the exact area enclosed between the curve y = e^2x and the lines y = 1 and x = 2. Can anyone tell me how I can go about doing this question, Im a bit confused at the y= and x=, you dont have to show me the working, just how I can go about doing it...

Does anyone have the files or can upload the files to megaupload or mediafire with all those past hsc trial papers collection for biology Thanks, muchly appreciated

Hi, I came across a problem which I have a little trouble with. Find the area enclosed by the curve y= x^3, the x-axis and the line y=3x 4. I did a rough sketch and then solved it as a simultaneous equation so x^3= -3x+4 then bring it over one side x^3+3x-4=0 but I get stuck on...

Hey :) I was wondering if anyone had any STAT past papers or practice tests apart from the ones on the ACER website because I need some practice before I do the test. Thanks

Hey when it comes to maths topic im pretty much good in all of them except for trig and I bomb out on it when I see a question that I don't know from it. Can someone give me any tips on how to study for trigonometry apart from doing lots of questions coz thats what im doing? (2 unit and...

Aye, I usually get questions with tangents and normals but this one confuses me o.0 The normal to the curve y=x^2 +1 at the point where x= 2 cuts the curve again at point P. Find the coordinate of p. Working out would be nice thanks

Hey ive got a question im confused with. A calorimeter containg 25 ml of water was at a steady 18 degrees celcius. 5.85 g of sodium chloride at the same temperature was added to the water and as a result the temperature of the mixture dropped to 15 degrees celcius. Calculate the heat of the...

Aye Im confused about moles if you have 4g of 2HCL would you find the amount of moles by: n = 4/(1.008+35.45) or n= 4/2(1.008+35.45) im confused which one to use.

Two questions. Find the simplest expression for each of the questions sec^2theta(1-cos^2 theta) and sin^2 theta cos theta + cos^3 theta I would appreciate it if you could show working thanks :)

Aye I dont get the whole deal of negative infinite limits. Could you please explain this example: Find lim x ---> negative infinite x^2+x+3/x^2 The answer is 1 from below... o.0

Aye, would any1 know how to solve this question. You are to show the decomposition of a carbonate by heat using appropriate tests to identify carbon dioxide and the oxide as the products. Describe how you selected the carbonate to investigate? I dont really know how to answer this...

Aye I started doing functions in the holiday and I came over this question: Find g(x-1) when g (x)= x^2+2x+3 but I don't get it , do I add -1 to every x value or something? The book says answer is x^2+2 Im in year 11 :rolleyes:
