    Question:
    In Part (c), how do you sketch the argument function. Why is it not the same as arg(z+1)? Usually arg(z) is a half line, but here it is a full line. I'm sure its the mod, but any explanation would be nice!
    TY,

    Why do edexcel only put the theta value in their mark schemes for when the question asks for the coordinates? Why not in form (r,theta)

    Yes, in the edexcel specification

    I don't the mark scheme usually award a mark for putting the coordinate in (r, θ) form, but there are marks for calculating both the angle and the radius.

    Which paper is this from?

    I've only glanced at it, but because it's a modulus, it can either be positive of negative.

    Take this example for instance
    |x| = 2. Therefore, x can either be +2 or -2.

    In this question, you have to possible cases:
    arg (z+1) = pi/2
    or
    arg (z+1) = -pi/2

    Hence you get the full line,

    My thoughts: a half line at an angle of pi/2 is just a vertical line. We only draw this above or on the real axis, as that's the only place where we can have an angle of pi/2 anticlockwise from the real axis.

    Anything below the real axis would be an angle of -pi/2.

    However, since it is a modulus, as you quite rightly said, the modulus, that is, the absolute value of the angle, is pi/2. So even points below the real axis (where they'd normally be at an angle of -pi/2) satisfy this.

    Relax, guys. Just chill out, there's nothing more than needs to be done.
    If I feel like I'm doing nothing though, which just stresses me out more. I'm gonna have a go with difficult questions in the exercises of the FP2 books (like weird complex number loci questions, polar coordinate graphs and the algebraic stuff). Also going to a revision session today but my teacher would expect me to have done every past paper and everything.

    Hey, have you been using pure algebra (that is, substituting x+iy at the start) or geometry (alpha-beta=angle, then using circle theorems) to solve these?
