I always notice that when you see the shuttle in orbit, the bay is poiting towards the earth instead of away from it. So you could say its flying upside down.

why do they do this?

is it safer?

This was my attempt. I got stuck..

x + 1
____________________
x^3 + x^2 + x - 2
-x^3 - x
____________________
x^2 + 2x - 2
-x^2 + 1
______________
2x - 1


The correct answer should be x + ( (x-2)/(x^2 - 1) )

If the prob is find
f (x + (triangle symbol)x) - f(x) for
f(x) = 2x^2 + 3x + 1

Do I plug in the f(x) equation (2x^2 + 3x + 1) every time I see an 'x' in the equation f (x + (triangle symbol)x) - f(x)?

A quadratic function, p(x)= Ax^2+Bx+C, is called a quadratic approximation of the function F for values x values near a, provided that the following three conditions are met;

F(a)=p(a)
F prime(a)=p prime(a)
F double prime(a)=p double prime(a)

For values of x near a=0, find a quadratic polynomial,
p(x)= Ax^2+Bx+C, that is a quadratic approximation for the function F(x)= e^(-x^2).

1. (3x^2 +2x-1) ^1/2 (square root, but i can't express it)
_________________
2^x +x

....i go to use the quotient rule but i'm not sure if you have to factor the top at some point or what happens with the variable in 2^x

2. (ax+b) (x^3 + 1/2x^2 +2logx) where a and b are constants.
....no idea on this one.

3. 1/ 3(2x-1)^2 +2^5x
....what happends with 2^5x, do you just find the derivative of the first part thenadd its derivative on to that?


Thank you, I appreciate this more than you'll ever know!!!

Lets say you were driving lost out in the mountains and all of a sudden you get snowed in. You sit there for about 3 days waiting for the weather to clear, but it never does. It appears as though nobody is coming to rescue you, and your cell phone has no reception there. You realize that the only chance of survival is to go out and find help on foot. Visibility is so low, you can't even see the sun in the sky. The weather is freezing cold. How do you navigate successfully to saftey without starving or freezing to death?

If all matter is energy, then is it theoretically possible to convert all of someones/somethings physical matter into energy, transfer it somewhere, and reconstruct it into matter? I know this would be massive amounts of energy to deal with, but could it be done? This would be far different from cloning and destroying the original like Quantum teleportation does.
