Again, the bullets represent 2 minute marks, approximately,
and this week we talked about complex numbers.
We'll talk about why it's a field. So if you don't know what the word
“field” means, I suggest checking out I believe Week 7 part 2.
We talk about rings and fields there.
The complex numbers are an example of a ring and also of a field,
something we will mention.
We talked about a couple of operations:
complex conjugation, properties of modulus.
We talked about polar coordinates, and we'll talk about converting
from standard to polar form
and from polar to standard form.
Actually we'll talk about polar to standard form next week I think.
