comment Computation of coefficients of Lagrange polynomials
Our homework is divided into the Lagrage part and then the Aitken-Neville and then Newton part. Therefore we need to try all methods ;-) But i will have a look at the paper you provided!

comment Computation of coefficients of Lagrange polynomials
I have implemented a Polynomial class which has the eval method based on the Horner scheme. Do you think, that i should use this? My first thought was to check whether i can get the coefficients with a more efficient algorithm rather then evaluating something... furthermore, while writing this, i need to remember the exact task. We must create the polynomial without a specific $x$. That is the reason why we have a Polynomial class. This is where my intention comes from to directly compute the coeffs.

comment Computation of coefficients of Lagrange polynomials
I could do that, but want to avoid that. We should implement this in Java for our Numerics lecture and we learned that it is a pain to derive as there many small errors can extremely influence the result! So i wanted a "small" expression that can be easily evaluted.

This notation is weird I know, so i will change this one. In a few minutes I will accept your answer, when the system allows me to do so.

comment Limit proof of a sqrt-heavy expression with binomial formula / sandwich-rule
@CaptainGiraffe: By obvious I mean that if you think aboout it, there is something about this idea. Furthermore I checked the limit with Mathematica and know that $\sqrt{2}$ is the solution.

+1 for the explanation of the method my fellow students used! However, as you already mentioned, I sticked to the conjugate quantity method which was much easier ;)

comment Limit proof of a sqrt-heavy expression with binomial formula / sandwich-rule
Although I never heard of either these methods, the first one seems the most convenient and human-readable one which solves my problem here! After reading the Wikipedia article this will be the solution I will use. Thanks!

Interesting approach, but the other hints were much easier to use. Sorry.
