Science & Mathematics - 3 September 2006

I just started AP Calculus BC this year and it really bugs me when i am given rules with no explaination. So yesterday i figured out proofs for many rules like the Power rule for finding derivatives. So i was thinking this morning and i had used my answer for the derivative of y=lnx and y= e^x in eachother. To find the derivative of e^x i assumed the derivative of lnx was 1/x and to find the dirivative of lnx i assumed the derivative of e^x was itself. which i didnt like very much because its kind of like an endless loop of assumptions. So, i saw that you could find the derivative of e^x using the simple definition of a derivative. but that required the assumption that the limit of (e^x-1)/x as x approaches zero is one, but i could not proof this assumption algabraicly only by graphing. So if someone could please show me how to prove this, or simply show me another way to prove my two original derivatives without using the answers for eachother in both of them. you can use the answer

I hardly believe their stomach is not proper for their consumption. I know they do eat sometimes grass for "medical" reasons, but could they live without meat? What if there's no prey? Would they eat fruits to survive?

I mean the energy gap shift calculated by Owen and Scalapino in superconductor materials in[Phys.Rev.lett.28,1559(1972)].i need a solution like the Fig.1(b) of this paper which includes more graphs for a larger range of n,or more n values.is there a paper which can help me for this or a computer program to solve equation(7) of this paper?

i just wanted to make the question more intriguing? :)

but anyway, if u just had a blood transfusion, of course your dna is different from the blood to be injected unto u.. (i know, red blood cells dont have dna, imagine platelet..) what is the process it takes for the DNA A (donor) to become DNA B (yours)? how long would it take for the DNA A to acquire your DNA?

* this is a seriously scientific question.. =)

I found a picture on the Net while trying to identify a small snake we found in our home. The picture shows a large mass inside the belly of a snake. There are pictures. 2 where you see the bulge and the third shows the open belly with a human body inside. Check it out and tell me it's a real!!!! Have you ever heard or seen such a thing. If yes where? And please No Hollywood Movie references.

Check this site.
