[Editor's[0] note: This entry was written yesterday.]
1: Correct.
2: Correct.
3: Correct.
4: Rather than actually *think* about the problem and realize it was falling-ladder (which I'd forgotten, but could easily have rederived), I decided to assume the things were segments, though I should have immediately seen that was untrue.
5: Couldn't figure out how to do it, at all.
6: Somehow, I didn't think of the idea of picking the digits first and then arranging them. Result: no answer, but with a bit more time I would have come up with a wrong one.
7: Calculation error. That's the only explanation.
8: GAH! GAH GAH GAH! I PUT DOWN AN INTERMEDIATE RESULT AS MY ANSWER! *bangs head on wall*
9: ...I had the correct expression on my paper in front of me. ½²*¾*½. And somehow I got 3/8 out of that.
10: Don't know what the error was. Probably calculation.
11: Couldn't solve the cubic I got.
12: I didn't think about it carefully enough and used the wrong series.
13: Correct.
14: Very close, but made a bad assumption. Funny, it still seems right to me...
15: Don't know what the error was. Probably just did it completely wrong.
So, with an index of 166½, no USAMO for me...
In other news...
I finally got to see Dr. D's giant microbes! I went to him during meeting time (yes today was a meeting day), and he just told me to go away, but I went again during last 3 mods, and I got to see them! Yay! Oh, he bought *all* of them. :D
Haha. M&M's and Coke work surprisingly well for headaches. Or at least for that headache (see previous entry). Somehow I doubt it generalizes too well.
