Last Thursday’s lecture notes are posted in the Documents tab. Perhaps you’ve seen them. Also posted are the solutions to your second exam. Your grades are up, too. If you want your test back you can get it from the box outside my office at any time. There are also a bunch of graded homeworks in there. 

Some statistics from the exam:

75th percentile:     84.25

Remember you have a homework assignment due Thursday; it covers material from last Thursday’s lecture. Office hours this week will be as 

If your textbook is like mine and has some sections omitted, you may seek supplementary material. Jim Hefferon has written a linear algebra textbook that is available for free here.

Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.

Though wise men at their end know dark is right,
Because their words had forked no lightning they
Do not go gentle into that good night.

Good men, the last wave by, crying how bright
Their frail deeds might have danced in a green bay,
Rage, rage against the dying of the light.

Wild men who caught and sang the sun in flight,
And learn, too late, they grieved it on its way,
Do not go gentle into that good night.

Grave men, near death, who see with blinding sight
Blind eyes could blaze like meteors and be gay,
Rage, rage against the dying of the light.

And you, my father, there on the sad height,
Curse, bless, me now with your fierce tears, I pray.
Do not go gentle into that good night.
Rage, rage against the dying of the light.

– Dylan Thomas
