Homework: limits and ploting graphs.

I have a homework that is to study and plot the function f(x)=sqrt[1-e^(-x^2)].

The derivate of this is f'(x)=(e^(-x^2) x)/sqrt[1-e^(-x^2)]

And I have a problem with showing that the limit for the derivate as i approaches 0^+ and 0^- is 1/-1

Re: Metric versus US Customary/Imperial for Everyday Use

I would say metric in almost all cases. But then I live in sweden and have always been using metric. The only case when I prefer imperial is carpentering and referring to the dimensions of planks. Because I feel it is easier to say "a 2 by 2" instead of "a 45 by 45". As you notic...

Re: TSA responds to xkcd strip

The thing I feel is that the idea is that a explosive sealed in a air tight container (a water bottle) wont be detected with a sniffer. Therefore they have baned large containers. However I have never been searched with a sniffer which means that oldschool solid explosives are still relatively easy ...

Re: "Bag Check" Discussion

Nobody have mention on of the most common weapons on board. Tax-free alcohol. Sure you might not be able to hijack the plane but if you smash the bottles you have a stabbing weapon and if you ignite the alcohol you are gonna cause some trouble.

Re: Nationstates - Local affairs thread

I'm unlikely to let you in. Do you by this mean that you are unlikely to let me in for now but in a few weeks the sitution may have changed. Or that the sitution will not change and I becaus of my bad timing cant join. If this is the case I will remain on the fora. And in the xkcd region untill a b...

Re: Nationstates - Local affairs thread

I have problems with the private forum. I have posted a mask request and now it wont even allow me to see the public board (the ones you dont need mask requests to see)
Anyone know how to solve this?
