Introduction
Differential equations are both challenging objects at a mathematical level and crucial in many ways for engineers. In addition, linear algebra methods are an essential part of the methodology commonly used in order to solve systems of differential equations. This course proposes to combine a basic introduction to both linear algebra and differential equations. This should be enough to cover most of the cases of interest for engineers and other practitioners. Specifically, the main chapters covered in this course will be:
1. First order equations.
2. Matrices and systems of linear equations.
3. Determinants
4. Vector spaces.
5. Linear transformations.
6. Linear differential equations of order $n$.
7. Systems of differential equations.

Homework
We will follow an assignment sheet, and the homework will be assigned through WebAssign.
About WebAssign: here are some introductory slides. You can access the system by clicking here.
Note: WebAssign does not allow late homework.
WebAssign problems usually due on Friday at 11pm.
Hand-graded problems usually due on Friday at 1:30pm.
I cannot accept late homeworks after the graded HW are returned to students.
