and so to specify the direction, we will have this angle, You have to say in whatĭirection do you have to go a distance of r to get to z. So for example we could give the distance from the origin to z, so let's call this distance r, but that distance by itself Real and imaginary parts, essentially the coordinates here, let's think about giving a direction and a distance to get to z. Now what I want to thinkĪbout are other ways to essentially specify the location of z. So z is real part negative three, imaginary part two. Part is negative three, so we could go one, two, three So, this is our imaginary axisĪnd that is our real axis. So first let's think about where this is on the complex plane.
Let's say that I have the complex number z and in rectangular form we can write it as negative three plus two i.
