In this lecture we found that there is more than one way to represent complex numbers.
Using polar coordinates to represent a complex number really highlights their rotational nature and made multiplication and division much simpler than using the Cartesian form we looked at in the previous lecture.
Which view of complex numbers do you prefer?
I think we are missing the lecture in which the polar notation is explained. 3+2i = Sqr (13) angle 33.7. I didn’t find this part explained in the previous lectures.
Hi @Alejandro_Borge1, we introduce the basics of polar form in the “Complex Multiplication” lecture.
All we’re doing here is representing our complex number in terms of the magnitude and an angle.
In this example, the magnitude is;
√(3² + 2²) = √13
and the angle is;
atan(2/3) = 33.7°
I hope that helps clear things up for you.
when dividing points how do we know which point should have a subtract operation assigned to it?
