All right, to plot negative 3 minus i on the complex plane, just going to be the point a, b.
00:12
And in our case, a is negative 3, and b is negative 1.
00:21
So we just go to the plane here, and we plot negative 3 on the real axis, negative 1 on the imaginary axis, and that point is right about here.
00:34
Now to find its trigonometric form, we need its absolute value r, which again is a squared plus b squared square rooted.
00:49
So we use negative 3 for a, negative 3 squared, and negative 1 for b.
01:08
That simplifies down to square root of 9 plus 1 or just square root of 10.
01:18
Now, a tangent of theta is a, and b again is negative 1, a is negative 3...
