    if i go through all the past papers, solomon and practice papers for trig, do you think i will be able to do the one in the exam?

    i am so bad at it xxx
    You could do all the trig questions you like but wait until you see the exam and there's only like two questions worth a total of 8 marks for 'em.
    All that time revising....

    Anyhow Good Luck, I'm doing it aswell.:woo:

    sorry but also how do you get from this:

    x = siny

    To this:

    1 = cosy\frac {dy}{dx}

    Not sure if im right but after looking at it for a little whiel since all of the terms are X^2 the minimum occurs when x=0 and then after that it just increases. When x=0 y= 3

    So the range is X bigger than or the same as 3?

    Just want to wish everyone the best of luck for tomorrow. There are these videos a guy makes on youtube which might be a good way to spend the final night before the exam, check them out: http://www.youtube.com/user/ExamSolutions (he does all the modules, so just search for the C3 ones) (:

    Try not to do TOO much the night before
    Cape! It has been far, far too long since we've spoken. Though in honesty I don't blame you for leaving TSR for a bit.

    So slightly off-topic.. did everyone get the offers they want
    No. I got bummed over hard.

    Looking forward to C3. Been getting around high 80's low 90's in all the papers I have been doing. Hopefully it is a fairly simple paper with not much of arcsin etc, missed the lesson on those and never caught up...

    sorry but also how do you get from this:

    To this:

    1 = cosy\frac {dy}{dx}
    basically, differentiate siny (which will give you cosy)
    so, now, you will have dx/dy
    in order for it to be dy/dx, you have to do 1/cosy (and then proceed as I explained earlier)
    What Pheylan's done is slightly different, but has the same concept (I think that's where the dy/dx=1/dx/dy comes from).

    Solomon papers are papers written by solomon press. They're harder than the actual papers and range from A-L (in increasing difficulty). You can get them from Here

    Well done

    Thanks sooo nervous about making the grades though
    hehe, Thank you!

    I'm sure you'll make them - they wouldn't have chosen you otherwise (they weren't exactly nice this year.)

    1910. TOTALLY messed up CR. I actually have to retake the SAT this Saturday... I'm so scared ;_; I don't think my vocab and critical reading skills improved
    1910's still pretty good, 1st time round! I hated CR... with the amount of maths you've been doing, you might be able to get an 800 on the maths section and then not have to do superbly on the CR section. Do the practice questions on the collegeboard website. And do the Question of the Day (it helps a lot more than memorising words).
