Since you have already posted a similar question on this newsgroup few days ago  and also you are asking the same ambiguous question on MathForum , it is hard to tell what kind of help you are seeking? (Note that comp.soft-sys.math.mathematica is a newsgroup dedicated to the computer algebra system (CAS) Mathematica.) So are you seeking help about . Mathematica . the concepts involved in fractional calculus . some specificities of the function 1/log(x) Also, . What about the previous replies you got? . Have you investigated them? . Did you try anything by yourself? . ... At any rate, it would be useful to restate your query in a more precise way, to show your work and/or attempts, describe any difficulties faced, give relevant background information, ...
