I found a fossil in a rock, the rock is about 25' deep in the earth and i dug it up. I have the rock and it has seashell inprints all over it. I scratched out a soft spot of clay in it and a small shiney black clawlike piece came out. It looks like a cats claw that is straight and is about a half an inch long.

I was watching a show on dinosaurs and they were showing a graphical representation of a meteor hitting earth. So I was thinking, if a large meteor was heading towards earth today how much time/notice would we have? How do you think our governments would deal with it? Would it unit countries at war or would they just leave it to the US to deal with?

For example:
* Is it better to live on the top floor in an apartment with surrounding asphalt/concrete than to live in a villa with a garden?
* Is it preferable to live close or far from the ocean?

All tips are welcome (the question is regarding a subtropical part of the world if that matters)!

Shouldn't the derivative of this be (cosxtanx + sinxsec^2x)? My book says (cosxtanx+secxtanx). Why!?!? Am I missing a trig identity or something? I'm trying to learn calculus and it doesn't explain why at all! Please help and thanks in advance!
