I dug up this old thread because I have a similar question for all you math geeks out there. 
-------------------
I received this problem last class in Calc II
Given R={(x,y)| y=1/(1+e^x) , x=0, x=b, y=0} Find the area of region R as b ->infinity
So I set it up, integrated and all that good stuff. I got ln2.
If anyone is bored, why don't you give it a try and see if I'm right. I'd appreciate, and if your like me you might have a good ol' time doing it. |
