MA242 A1 - Linear Algebra - Fall 2009

Lecture: T,Th 3:30-5pm in PSY B55
Discussion: M 1-2pm in PSY B49

Welcome to the Linear Algebra (MA242, section A1, Fall 2009) course webpage! If you need any information that you can't find here, please email me.

  Linear algebra is the subject that made me want to become a mathematician. When I was an undergraduate, my linear algebra professor made me attend a research seminar on this paper, which you should be able to understand by the end of this course. In it, the authors use linear algebra to study the population dynamics of an endangered species of sea turtle. Among other things, their results indicated that it was important to protect the turtles from the adverse effects of certain types of fishing. In fact, they even used their research to help get legislation passed to do exactly that. For more information, click here.
