I am having a difficult time dealing with lists.
I have a list of data :
{{1,2},{2,3},{4,5}}
I want to do some operations on the second column only.
Such as +1, Sin[], etc to each element in the second
column. I admit I only have a rudimentary knowledge
of Map, Apply, Transpose, and Flatten. Any help would
be appreciated.
Also, I have data that needs several fitting equations.
One will be Exp[a x -b], another Exp[-c x+d], and the
last would be a polynomial. Then I would like to Plot
the data and fitting equations in there respective
regions at the same time. I have seen something
like this before, but I can't remember where.
Thanks
Richard
