    'Certification of Course Topics Studied' form?

    Just wondering if anyone knows if/where I could get a sample of this form? It's my understanding that the ACTUAL form is released by the Board later on in the year (though that could be incorrect) but I'm just wondering whether there's a copy from a previous year floating around or something...

    Compound interest question anyone?

    I got the same answers as hscishard: 1. There are 31 terms (months). You find this just by finding the amount of time between January 2007 and July 2009. (12 months + 12 months + 7 months) Each term, she deposits $400--making a total of $400 x 31 = $12 400 deposited into her account. 2. This...

    Syllabus Question: 8t^2=1-10t

    [Solved] Syllabus Question: 8t^2=1-10t I'm using the syllabus to make some notes for myself and 1.4(iii) has an example question I can't make sense of. The section is 'quadratic equations, including solution by factorisation and by formula' and the question is 8t^2=1-10t. As far as I can...

    Integration Q: Sums and Differences of Areas

    Oh, that is—I have the combination advanced/extension book, but the same chapter is also in the 2 Unit Book 1, I'm pretty sure.

    Integration Q: Sums and Differences of Areas

    Nope, I didn't make it up. Our teacher told us...but yep, it's in our textbook too. :-) 3 Unit Mathematics Book 1, Jones & Couchman. (Published by Longman.)

    Integration Q: Sums and Differences of Areas

    It doesn't matter which you subtract from the other, really—so long as you take the absolute value (because area can't be negative.) You get the same magnitude either way—only the sign differs. I'm almost 100% sure I'm right on this, but if I'm not please feel free to correct me otherwise. :-)

    Integration Q: Sums and Differences of Areas

    The area between the two curves is the difference between the areas of the two curves. (If you don't know which curve is above the other then you need to use the absolute value to obtain a positive area.) \begin{align*}A &= \{\text{area under }y=g(x)\}-\{\text{area under }y=f(x)\} \\ &=...

    How are you going?

    I've yet to actually start my BOW, so in relation to me, at least, you're doing fine. I'm planning to get a fairly good start on mine this holidays, too. :-)

    Integration of logs and exponentials questions

    I think that's what you would do in the second part of (b). No wonder I couldn't figure it out—we haven't covered it yet, haha! :-) It looks like it should be relatively straightforward, though. I got the wrong answer, but I forgot the function of a function rule or something and it should work...

    Show me your Pens!

    I am a stationery obsessive; it's true. I use a Pentel EnerGel Metal Tip BL17-A 0.7mm. I love them. :-) They're really smooth, really dark, and I don't think I've ever had any issues with smudging. (Apparently they're okay for left-handers to use but I'm not going to back that up; I wouldn't...

    Integration of logs and exponentials questions

    For (b), part i. : \begin{align*} \int_{0}^{ln5}\left ( \frac{e^{y}-1}{2} \right )dy &=\int_{0}^{ln5}\left ( \frac{e^y}{2}-\frac{1}{2} \right ) \\ &= \left [ \frac{e^y}{2}-\frac{y}{2} \right ]_{0}^{ln5} \\ &= \left ( \frac{e^{\ln5}-\ln5}{2} \right )-\frac{1}{2} \\ &= 1.19528... \approx 1.195...

    Integration of logs and exponentials questions

    For (a): \int_{0}^{2}ln(2x+1)dx \\ $Five function values means there are four subintervals.$ \\ \therefore h=\frac{2}{4}=\frac{1}{2} \\ \\ A \approx \frac{0.5}{2}[f(0)+2(f(0.5)+f(1)+f(1.5)+f(2))] \\ \approx 0.25[\ln1+2(\ln2+\ln3+\ln4)+\ln5] \\ \approx 1.99138... \\ \approx 1.991 $sq. units$...

    looking for name of artist!

    Yup, just found it on Wikipedia. You were right; his name is Mike Parr: (Mike Parr - Wikipedia, the free encyclopedia) Obviously not a great source for information, but a quick Google session suggests that he's your guy. :-) Hope that helps!

    Intergration Question

    For your new question: \begin{align*}y&=(x+3)^2 \\ \sqrt{y}&=x+3 \\ x&=\sqrt{y}-3=y^\frac{1}{2}-3\end{align*} I assume that's correct. It's all just a process of working backwards. (And of course, you don't need to use an indice instead of a square root sign, but it might make it easier...

    What is the difference between metaphysical conceit and metaphysical wit?

    I'm having a bit of trouble making this distinction as well; my current understanding (which is quite possibly far from correct!) is that a conceit is a kind of 'strained' or 'far-fetched' drawn-out metaphor, whereas wit is more general--unexpected leaps of intellect. So, according to my...

    Setting out Module A 'Exploring Connections' summaries?

    Hi all, I've been lurking on BoS for a while, but I think this is my first post. Wondering if any of you have any ideas on setting out summary notes for Module A. I have just gone through the process of typing up my handwritten (incredibly messy!) notes from Module A (we studied Donne/Wit)...
