(graphing question) I've tried adding the y snd x of points A and B and multipying the result by 3/8, but it won't work! How do i do it?? ( to get P if P in exactly 1/2 along lin AB, you add them together and divide by 2-multiplying by 1/2 also works.)

Excluding venomous reptiles and amphibians, I know deer kill many people in car accidents. But in a bizarre and utterly random curiosity, I'd like to read some statistics on deaths from animal attacks.

Apparently I have Stephen Colbert's fear of bears on the brain.

I have just bought student edition of Mathematica and I have no idea how to so some basic stuff. Could anybody please tell me how to "sketch several typical solutions of the given differential equation and highlight the one that satisfies the initial condition" using Mathematica? I have tried looking at Wolfram website but couldn't find clear explanation.
Could you please give me some example of the code for any differential equation and any initial condition you want.
Thanks!

Many beleive they have, and not taking that lightly. I ask to find out if anyone here beleives they have. I respect all people, and do not down those who beleive they have. This is a real experience for those who have had an encounter, many have testimonials that would shock others I am sure.

Please may you give me a few more than obvious reasons, to do with adaptation, competition, evolution... that explain why Pandas are endangered.

I already know that lack of habitat is one of the reasons, but any more?
