    X=0.1 so you get root of 7.1. Then just multiply the answer by 10 as the cubed root of 1000 is 10
    Of all the things in the syllabus, I actually think that question is the most baffling. Most questions if I do wrong I usually go "ahhh I get it" after like 10 minutes of attempting and exam solutions. This question just doesn't even sit with me.

    Any tips on finding out a vector of something like AB?

    say, you got AB on L1, how do you find the vector for it? is is b-a or a-b? I always get confused and end up having minus the angle that I find by 180..

    Its been said before but basically it will be given, sometimes they use synoptic AS, even GCSE links but there usually for 2/3 markers
    if its a 6/7 marker they would give you the additional information

    Remember that AB gets you from A to B. a + (b - a) = b Hence AB is the vector (b -a)

    If it asks me to differentiate something like 1/((x+2)^2)

    Can I use substitution (u=x+2) or would that not get any marks because it's not in the mark scheme

    Is that what you would recommend and then do the exam externally ?

    I see.. thanks I always get confused with the direction of my vector, which leads me to having to minus my angle by 180...
