Lecture notes from lecture #3 of [[MATH 236]]. Material covered: some properties of vector spaces, subspaces, sums and direct sums.

Properties of vector spaces

1. A vector space $V$ has a unique additive identity element, the zero vector ($\vec 0 \in V$).
2. Any element in $V$ has a unique additive inverse.
3. $0v = 0$ for any $v \in V$.
4. $a \vec 0 = \vec 0$ for any $a \in \mathbb F$.

Lecture notes from the first lecture of [[MATH 325]], taught by Anthony Humphries. In this lecture: information on the course (grading scheme, expectations, etc) and an introduction to ODEs, complete with a solved example.

Lecture notes from lecture #2 of [[MATH 236]]. In this lecture, we got a brief introduction to complex numbers, and were given the definition of a vector space (along with some examples).

Complex numbers

$$\mathbb C = {a + bi \mid a, b \in \mathbb R, i^2 = -1 }$$

Note that $\mathbb R \subset \mathbb C$.
