We're given the complex number negative 4, and the first thing they ask us to do is to plot this.
00:11
And so when we're plotting this, the real part goes on the horizontal axis, and the imaginary part goes on the vertical axis.
00:20
So complex numbers are in the form, a plus b, i.
00:25
A is the real part, so a is negative 4.
00:28
B, i, the imaginary part, so b has to be zero, because we don't have any, i turn in this expression.
00:36
So that means we're going to negative four on the real axis, and we are staying at zero on the imaginary axis.
00:45
So there's our plot of negative four.
00:49
Now they also want us to put this into polar form...
