    Probably 74 full UMS and 67/68 for 90.

    Thoughts on A* boundary and full UMS?
    I predict full UMS 75, 90UMS 69-70. I'd be tempted to guess 70 though

    Can anyone tell me how many marks I will get for this:

    So when working out costheta, I somehow got 15/20, and then I did 1/2absinc using the value of theta from that part, so I got like 2.65. Out of the 5 marks for the 2 parts, how many will I get? Because I believe I should get ecf marks.

    oh ****, I think I got 4 a) wrong. does anyone remember what the question was?

    Edit: nvm, I put e^(-2.5t+ln60). how much marks do you think I would lose? i'm thinking just A1

    Fair, hoping for 74 as the max then 😁

    cos(theta) was 4/5. Left it out by mistake.
    Got exactly the same but for 6b I bought the 3 up as a power and the same with the 2 and then used law laws to make them as a fraction in a single ln. Would that be fine?

    for Q6 on the prove that the integral = k (integral) sin^x i got 1/8 (integral) sec^2x. WHere did i go wrong and how many marks would i get for part B for carrying the k = 1/8 instead of using k=8?

    I found area instead of finding volume for q6b. And quite sure my area is right. I also wrote S(Area)=blahblah Lol. How many marks will i get out of 4. i had problem with time man **** or i would have corrected it.

    wasn't lambda = 16? then it changed to 8 outside the integral when you did the second part?
