    Should be an A* assuming your other modules can make it up to 480 over the six modules.

    hey, how many marks would I lose on question 3 if I did not put dy/dx after I differentiated the cos pi? I differentiated all the rest correctly, but this meant I also would have got part b wrong as well?

    Hey, can anyone say what 67/75 and C3 and 67-70/75 in C4 would probably be as a grade? If my other UMS adds up to 480 will that be an A* or an A?

    You might scrape an A*

    For 7.b,can you do y=8 minus the equation of the curve instead? Limits 0 to 17.5?

    No

    The integration method would have looked like this
    \displaystyle \pi\int_0^{\frac{17}2} 8^2dx  - \pi\int_{\frac12}^{\frac{17}2} (2x-1)^{{\frac34}^2}dx

    Since the limits differ, a single integral solution can not be performed.
