    Demento's Year 10 maths practice paper thread

    Unfortunately, I didn't sign up for it this year. I did the writing competition though. Actually a very nice idea. I'd be happy to contribute a few of my essays. I can PM you guys a pretty decent paper that I wrote for English about censorship - hopefully you guys enjoy it as much as I...

    Not a genius. :) I'll go through and take a look at some of the essays I've done in the past that might be able to indicate the difference between a good essay and a brilliant essay that leaves a mark on your teachers. (ofc - not all my essays are brilliant, takes a lot of effort and dedication)

    Demento's Year 10 maths practice paper thread

    I can give it a go in making an English paper (going to vary due to what people see in schools), but a lot of my questions are just going to be in the same style and format that I follow with my school. I can provide you guys some extracts and questions to answer and give a go. Marking wise, I...

    Here is the link for the exam that you can download (appreciations go to twinklegal for doing the sharing): http://www.mediafire.com/view/?4mzelj1ik39clf6 And below are my solutions that I have for the exam (I've allocated what deserves and doesn't deserve the marks)...

    Demento's Year 10 maths practice paper thread

    Proved the sum and product of roots using quadratic equation, based on spiral's answers, I think I am correct. For my maths paper, I will post solutions once I can get somebody to combine all my PDF files into one to share onto a website link. Give me about a day and you can mark your papers...

    I respect the fact that he comes up with all sorts of interesting problems. It takes me days and holidays to think of like two questions - the penny dropped in one of them when I was on a ride in Seaworld.

    Here is your chance to impress me and beat me at my 'own game'. Maths was never my best subject, although I wish it seemed so to me. :(

    I question Carrot's 3U and 4U papers.

    Has fawun gotten up to absolute values and such? I'm pretty lost in some of the symbols myself - probably haven't learnt it yet.

    I call it 'systematic listing' to suit a certain case. Don't make it sound silly. Example: Draw up a table of values if that works.

    Oh, I see. Thanks for pointing that out.

    How about if I had this first: r=\frac{2\pi r}{\pi r}+\frac{4r}{\pi r}

    My thanks and appreciation go to twinklegal, who was able to upload the PDF files into one to share for all students keen on trying out a year 10 maths paper I made. Below is the link: http://www.mediafire.com/view/?4mzelj1ik39clf6

    Nvm, I simplified it too quickly. \frac{1}{2}\pi r^2 = \pi r + 2r \pi r^2 = 2\pi r + 4r \pi r^2 = 2\pi r + 4r Now divide the equation on RHS by \pi r, and you get: r = 2 + \frac{4}{\pi} Combine fractions. r = \frac{2 \pi + 4}{\pi} Ignore mine, to type it out, it's pretty much the same...

    Alternatively, just a faster approach I found: \frac{1}{2}\pi r^2 = \pi r + 2r \pi r^2 = 2\pi r + 4r \pi r^2 = 2\pi r + 4r Now divide the equation on RHS by \pi r, and you get: r = \frac{2 \pi + 4}{\pi} Edit: excuse my fail latexing. Typed it all wrong.

    Edit: BOS party at your house if you're correct.

    Remember: You want to make 'r' the subject by itself. Edit: No, he doesn't want you to square root it on the last line.
