    Do you know how many marks 3c was worth? I didn't notice the sign change
    2 marks. I remember adding it up as one of the questions I've potentially lost marks on.

    (1/2)(1/sin4x) = (1/2)cosec4x

    I am sure it was the x coordinate of turning point of e^3x cos(4x)

    Eh, it was as little bit of tough algebra, I think it was 4 marks.

    no as the range was pi/4 and pi/2 and this was the only value that fell inside this range.

    How many marks will I lose if I



    1) for question 1b stated both a=6 and a=-5 forgot to reject the answer a=-5

    2) for question 2b messed up the range and stated that -rt5<x<rt5 instead

    3) for 6b messed up differentiation so got the wrong dy/dx but otherwise method of finding normal and stuff was right?



    Will I be able to get my A* in this paper? 🙇🏻

    Wouldn't there be two turning points? Did it ask for a particular one?
