    for the partial fractions question instead of writing the A and B in fractions I wrote it was -2.5 and 4.5 would i lose marks?

    partial fractions and binomial expansion, i think answers are as follows:
    A=-5/2 B=9/2
    -1+7x-22/3x^2
    not sure on limit, think some people have something like mod x < 4/3
    I think the two modulus values were;

    |x| < 3/4, |x| < 1/2

    which means that |x| < 1/2

    what was the binomial expanasion answer i got a really messy one ayone else?

    Did anyone else get 9/2 e^4 for their gradient at (ln2, 1/2)?

    Does anyone remember what the fractions were that had to be expanded for binomial?

    what was the gradient when you use these to find dy/dx
    sorry they were x=(4-4e^2-6t)/4 y=e^3t/3t and gradient 1/2e^4

    Thanks bud. People like you amaze me. For the binomial one when you say 22X^2/3 , does this also mean 22/3*X^2 ?
    Yeah, pretty sure its the same

    Only thing I think I got wrong was the binomial because for some reason I had 3/4 instead of 3/2 on the outside of my second expansion but pretty sure I expanded them right inside and for the other one, how many do you think I lost, I think that's about 3/4 marks because of that.

    Can we please verify if 1/5 or 13/35?

    (Original post by Adam_98)
    All the answers I can remember putting. No idea if any of them are correct so feel free to comment:

    A= -5/2
    B= 9/2

    -1+7X-22X^2/3

    theta = 99.6° , 260.4°
    (Rejecting cos0 = 1 as solutions are outside the range)

    -3X +2+9/(whatever the factor was)

    9/2ln3-69/2

    181grams
    330days

    P=2/15

    R=1/3

    S=4/15

    CosX=1/5

    (2,0,-1)

    C = (8,-18,-31)
    D = (-4,18,29)

    e^4/2

    sin3x-3xcos3x = ......+pi

    In the parametric gradient would it be ok if i left it with e still inside it and stuff, I mean the question asked only for exact value I don't remember it saying simplest form?

    For the last part I think you got |x|< 0.5 and |x| < 3/4 but as 0.5<0.75 you just put |x| < 1/2?
