    Was there any integration at all ? I didn't spot any. There was one question were it gave the differentiated form of dy/dx and it said find the equation of it. Do you put it in the form of "y=......ect.." you know when you get the curve of the equation then you differentiate to get dy/dx please tell me this is right, you do the opposite don't you ? tell me if u dont understand my concern

    you integrate dy/dx and got something like 2x^5-2x^3+5x+C
    =>y=2x^5-2x^3+5x+c
    =>solve for C e.g C=-2x^5+2x^3-5x-y
    =>you should've got c=-1
    =>y=2x^5-2x^3+5x-1


    (the signs might be wrong but im 100% certain of the -1 at the end)

    I did that but I didnt put C and C=-1 Woop defo got some there then huh Cus I differentiated it back and wrote "Hence, dy/dx = 10x^4 - 6x^2 + 5

    I'm a little bit unsure about your case mate. Here's the thing by writing y=......+C
    C=-1 you are correct and would get all 5 marks for that. Although these kind of questions have that "take the last line as the answer" so you may drop the marks if your last line isn't y=.......+c C=-1 or y=.......-1

    It was a coded intergration.
    You were given the f'(x) of a function.
    And from that we have to work out the rate of change?

    Then it tells you to work out the equation of the curve.
    You intergrate it, BUT it's 5 marks so you have to work out +C by subsituating the points of P (1,4)??? Into the equation to get -1 as C

    I don't think its ever been 65.. It'll probably be 62-63 not 65

    That was part 1 question wasn't it express it in form of y=mx + c i got something like y = 9x and something else, but the last bit(Part 2, 5 marker) I didn't show any working out I just put the correct answer excluding c= -1 as u say

    Hopefully if this question was excluded from 'Consider the last line their answer' then you would get all 5 marks.
    But it is highly likely that the last line will be considered your answer so if your last line isn't y=.........+c c=-1
    then you may be looking at around 3 marks

    You were just asked to draw the curve showing where the curve crossed the y axis. No need to perfect vertex.

    I suppose 3 is better than none, although on some past papers it says "Condone +C"
