We have the complex number negative 4i, and we want to graph this on the real and imaginary axes, and then we want to find the polar form of this.
00:18
So the real axis is the horizontal axis, the imaginary axis is your vertical axis.
00:25
Well, complex numbers are in the form a plus b, i, and it's a and b that we use to plot our, coordinates here.
00:36
Well, a is zero and b is negative four.
00:39
So i'm going to zero on the real axis and then down to negative four on the imaginary axis and there's my plot.
00:53
For the polar form of this, i need two things.
00:55
I need the radius, which is the distance from the origin down to our plot.
01:03
And i need theta...
