    So how?

    Only look if you're sure you want to see it

    \frac{1}{xlnx}=\frac{\frac{1}{x}  }{lnx}}
    .

    Edit: It seems as though people weren't too keen on the spoilers so I've removed them.

    \frac{1}{xlnx}=\frac{\frac{1}{x}  }{lnx}}. And \frac{\frac{1}{x}}{lnx}} is in the form \frac{f'(x)}{f(x)} so it is a ln integral

    Any of you guys have any idea how hard they can make the vector questions...

    like the final part may be related to the equation of a circle ... but can it get harder than this ? (I find that hard already)

    Inclusion of circle geometry even...

    Yeah probably depending if Kate decides to make an appearance in our c4 paper in a form a vector question looool

    Oops, then just ignore the majority of what I've written I assumed you did AQA because they're on the same day
    Every examboard of Chem5 is in the same day!

    Do you have an example of a circle one? Not sure if I've seen one of those before...

    I guess it is possible they could, as there you know everything you need to solve it. But I highly doubt they'll put it on there. And if they did (which they almost certainly won't), it wouldn't be worth more than 2 marks as there isn't really any working you need to show, you can just go straight from the question to the answer.

    Hi! Related to circles?! Which Q did you see this on? Vectors tend to be really tricky qs, there's one on page 83, Q6 in the textbook, it's actually easy though, but you might be able to do it anyway

    It's been quite a while since I did the paper, but I didn't really bother much with it I find vectors so hard

    & I think it was in Jan 09 !

    Jan 09 paper I will have a go thanks !

    After C3... I am expecting all sorts of funky stuff to come up But I think these "different" questions Edexcel are putting into their exams now, are hard to be prepared for

    Kate was standing at position J which was (9i + 4j + 0k) with respect to the origin O where her camera was, she quickly needed to get to position M (17i -7j -2k) where the marathon was starting. The road she was standing on was perpendicular to the road where the marathon was starting. Calculate the minimum time it will take her to reach the marathon after collecting her camera assuming she walks at a rate of 0.00215m/h?

    Hahah, but last question wasnt the hardest at all. In my eyes it was q7. didnt get similar triangles at all! Coupled by silly mistakes with ln questions..

    Exactly that because no matter what it's unlikely that people will have come across the funky stuff they put in anywhere before as it's all about application:rolleyes: So I guess the best thing to do, is what I think let people down in C3, is to not panic & try to take it slowly (but no too slowly) . Easier said than done, definitely.

    That's what I do, it makes sense to me!
    i recenly did a solomon intergration question where ln(something) became negative but they took it as positive because they used modulus, i heard in c4 exam conditions they wont do this?

    No, its fine, I know the formula I just suddenly had no clue cause I never saw the style of question on the edexcel cause it was asked on a solomon paper.

    But thank you for your concern
    Im sorry i was just stressed at the time :/
