Lecture 2 and Lecture 3

Basically, these two lecture has no much difference. The only difference is the venue, because lect 3 is the replacement class.

Before lecture 2, I had prepare my self to pre-read the lect notes. So I won't be too blank during the lecture. During lecture 2, I feel that the topic that Mr.Saadat explain is easier to be understood. From now on I'll try my best to pre-read every lecture.

Sadly, I can't pre-read lecture 3, coz I was so sleepy to read them. So, during lect 3 I feel a bit lost.
I'm happy Mr.Saadat was inserted more example in the explaination.

I hope the class will be come more enthusiastic and energetic.
