SLOG for week5

Something new: 

1.Proof using contrapositive

2.Proof using contradiction

3.Proof for existence

4.Proof about a sequence

Something enjoyable:

learned to use contrapositive when the reverse direction is easier to prove than the original.

learned to proof layer by layer when facing a problem containing several different structures.

Something frustrating:

1.TERM TEST: Although prof. Zhang said that it wouldn't be too bad if I did bad in the test, I’m still worrying about it.

2.Structures of proof: Still not quite familiar with them. It’s difficult for me to separate the proof into different parts.(like which part belongs to which assumption blablabla…)

Solutions:

1.Pray.

2.Practice, Practice and Practice.

Material covered those weeks:

Not bad. Only need to practice the proof structure more.

Achievement?

Got full mark on quiz3.(Hope my term test’s result is as good as quiz’s!)

Tutorial&Quiz:

pretty good~ I can always get some new understanding after each tutorial!

That's all for my week5. If anyone has suggestions for me on writing a SLOG, please leave me a comment and I'll appreciate it! Thanks a million!
