    That's right.



    (If only I'd known that this morning)
    I forgot aswell, so i pulled out the formula booklet and checked it to make sure

    I'm sure it will be below 60 :L

    I'm getting somewhere between 64-66
    and hoping for 92 :L
    I hope you're right!

    i did say most calculators do integrals now..
    it lets you know you've gone wrong, so it does help
    so that was a complete non-point, why even mention it
    Considering the question directly specified how the question it should be done I really don't think the calculator confers the advantage you suggest.

    It's still unfair that some people have calculators can do this work out integrals and cubics (although most people now have calculators that do the latter)

    thats a stupid point anyway, you can get a pen for less than 50p, if you couldn't afford one the exam centre would give you one
    where as graphic calculators are £80 new which puts many candidates off, so the people who can afford it have an advantage
    Graphic calculators give minimal advantage. The only main advantage is a bigger screen. Graph sketching isn't really useful either, especially if it doesn't tell you to sketch one. And the ones that solve integrals and cubics are cheap, the casio silver ones are £14.

    It's not cheating if it says graphic calculators are allowed. I could walk into a any exam and complain why only those that can afford a pen deserve advantage.

    It's not about the price as our school lends us one, but I don't use it because I have some dignity, and would rather achieve a grade based on MY ability rather than my calculator's ability to do algebra and plot graphs. In my FP2 exam there were graph questions, and I don't think that it's fair that some people have the advantage of using their calculator to sketch high mark questions whereas some people actually have to work it out for themselves. It may not be cheating, but it certainly represents a lack of confidence in someone's "math capabilities" (so to speak).

    edit (bold)
    you may have been able to get it right, but im sure lots of people who were unsure could have used a graphical calculator which would have given them a better idea of the answer
    No, a graphic calculator does not give you a better idea. You still get a numerical answer like any other standard integral solving calculator. Do you even own a graphic calculator??

    Completely agree!

    For the question where it was (1/4)ln(3), would it be acceptable to right (1/2)(ln(root3)), as it didn't specifically say integers, it just said express it in the form alnb. Also, for the integration by substitution one, did it require you to put it back in terms of x, or could you have left it in terms of u? Thanks

    Can some one show how to do the 'show that' binomial question ?

    Posted from TSR Mobile
    x/(1-x)^3 = x(1-x)^-3

    (1-x)^-3 = (-x(1-1/x))^-3
    (-x(1-1/x))^-3 = -1/x^3(1-1/x)^-3
    x . -1/x^3(1-1/x)^-3  = -1/x^2(1-1/x)^-3

    He'll most likely post a link on here to a new thread with his answers.

    That's what I've put - it's correct
    :L it would be really harsh if they drop you a mark for that - that's just them wanting you to fail!

    Well technically 1/4 isn't an integer anyways, so them specifically saying integers would rule this out :P I believe 1/2 ln(root3) would be marked correct, as they never gave any constraints.

    and I still think the only advantage with the graphic calculator is that for the graph sketching questions - you can check your answer and put your mind to rest for that question should you get it right - you would still have to work out asymptotes and stuffs.
    Or it could show that you did something wrong and it could be frustrating because you know that you got it wrong hence may affect your performance for other questions.
    so double edged sword really.

    Are you talking about the \frac{1}{2} \ln\sqrt 3 question? I think it would be very harsh, I'd just like to get some other opinions

    yes - I wouldn't think about squaring it to make it look pretty in an exam anyway haha.
