For the proof for multiple roots theorem, what is the reason we cannot let Q(a)=0? Thanks in advance.

I tend to type my notes a lot at home but my computer is located in the lounge room (parents don't trust me) and my little brother always turns the TV on even when hes not looking at it. So I was wondering if it would be worth it to purchase one of those little netbooks so I can use it in my...

I know this is off-topic but why do you need 96+ Atar for BCommerce and BArts, I thought for USyd it is 94.5. Unless you are aiming for 96 regardless of course? I'm just wondering because I'm also aiming for the same course in Uni.

Which one are you better at?

solve sin3x=cos2x

Hi, planning to enrol now for year 11 for 3u and going on to 4u next year. Who do I contact to enrol?

Sorry I meant methanol! Yes I read the document. But I dont understand why the molar heat of combustion increases but the normal heat of combustion decreases. EDIT: Don't worry, forgot to read the molar heat of combustion part! Thanks! The doc cleared up a lot of things for me!

So if enthalpy decreases wouldnt that mean heat of combustion increase? And from that table it would mean that the more carbon there are the higher the heat of combustion. I'll just base my hypothesis on the theoretical values and account for the discrepancies due to incomplete combustion...

For my independent investigation, I'm doing the heat of combustions of hydrocarbons. I was absent from school on the day my teacher explained to the class on how to perform the investigation. I have already researched the topic but I am still unsure about something. Is it true that if a...

Let say I'm going to do 12 units in year 12. I score very high for all 10 units except for english(which is compulsory) in the externals which I scored very low. Does my score for the top 10 units count in my atar? or is it that English is taken into account regardless and replaces two of my units?

thanks!!!

Hi, Can someone give me an example for finding angles of inclination of the tangent and normal and help me do this question: Find the equation of the tangent and normal to the graph of f(x) = x^2 - 8x + 15 at the (4, -1).

I have my own copy of Jacaranda Physics 1 text(because my school does not have enough copies) and its pretty good though I find the book to be a bit less detailed than other text books I have seen. Another criticism is that it does not have solutions for number based questions(just answers) and...

Thanks!

How can you mathematically test whether a relation is a function without vertical line test?

Doesnt exactly cover all the different types of questions.
