Subject: Homework...
Just worked possibly the lowest temperature ever recorded, and it's to do with the LHC (Large Hadron Collider), liquid helium is used to cool the machine to its operating temperature of.. wait for it.. 1.9 KELVIN (-271oC)!
Contour integral over (z+3)/(z-1)^2. Contour: |z|=2 (circle with radius 2 with centre 0)
(z+3)/(z-1)^2=4/(z-1)^2 + 1/(2-1)
1/(2-1) leads to 2PiI, but what to do with 4/(z-1)^2?
(z+3)/(z-1)^2=4/(z-1)^2 + 1/(2-1)

I don't know the answer, that's why I'm asking, but Cauchy says:
2PiI f'(z0) = Contour integral over contour c of f(z)/(z-z0)^2
f(z)=z+3 --> f'(z)=1 everywhere so the answer would be 2PiI.
2PiI f'(z0) = Contour integral over contour c of f(z)/(z-z0)^2
f(z)=z+3 --> f'(z)=1 everywhere so the answer would be 2PiI.
could anybody help me with my homework, I´m writting a 3xA4 essey and I just run out of ideas.
The question is: what does it mean to be an European?

yup, that is pretty bad one.. will be a long night for me I guess..
wouldn´t be wise to mention eurotrip in my essey:pP, unless, there are some good quotations to use:P
.. seems like no one knows the answer:/

It's bleeding annoying to be North Western European at the moment (for some people) with all the snow.
euhm you are estonian right?
If your parents and grandparents hadn't sung together and revolved you would be maybe still Rusians... think about that! write about what europe can give you and what Russia can't... or the other way around...
