I have a list with about 8000 pairs of values like
and I want to have a list with the derivate of the function using DerivativeFilter[ ] upon the entries. To do so, i want to extract just the second value of the list, i.e. obtain
I didnt find any solution to my problem to do that easily.
Also: Is there an easier way to gain the derivate? And another question: How could I act with an operation only on the first or second variable of the pair, for example
Thanks for the help!
