(All integrations are in respect of dx)

Its known that:

Now if we integrate both parts we have that:

and correct me if i am wrong but:

So

And comparing 1 and 2

What am i missing here?

Thank you a lot

Thank you

Indeed this explains the result.

However i rely on the fact that is the "neutral" element in calculus (as unit is at multiplication / division).

So what about if we derive the initial relation???

I thing we lead to a similar inconvinient result.

of course in this last case (for negative n) can be defined properly so the last relation to be valid - Dec 5th 2009, 06:57 AMDefunkt
