Lecture 07

I have trouble explaining the simplest things. Today, I tried to explain how to solve a system of linear equations in a systematic way. It's supposed to be a simple concept, but I don't know how to explain in a simple way. In any case, I don't know whether they find it to be boring or difficult...heh.

I tried to type up the solutions to assignment 2 tonight, and found it to be so tedious... I didn't know that it would be so tedious...poor students...hope they're enjoying the course...heh.

Looking ahead, I'm kind of concerned about switching vectors from horizontal to vertical... And vector spaces scare me too... Hmm...
