    [SOLVED] Simple Clarification of Complex number

    Hey,
    I was just wondering what I am supposed to draw when a question asks to find the points that are formed by |z-w| and it has no = c part. Therefore it is not a circle. I have values for z and w .

    Am I supposed to mark the real number that is produced by this absolute value?

    Question:
    Show the set of points which represent |z-w| on an Argand plane.

    Thanks

    Do you have values for z and w?

    Argand Diagram -- from Wolfram MathWorld

    This should be useful.

    Yes z and w are two complex numbers
    z = -2 + 4i
    w = 3 + i

    There is only one value for this subtraction, so you only get one point on the Argand plane. And, as you say, the result will be real, so it goes on the real axis.
