In Response To 'Re: plot exp with integral'
Merci for your indications.
But there is a problem I really don't understand.
If u see, the function to plot is asta=t/t0
and the difference between t0 is in fact t when B=0.
It means asta=1 @ B=0 and from the graph is far away from this.
I think there is something strange happening with that integral. Anyway, I don't know how Mathematica calculates this in B=0, because lB is infinity there; is it making a limit or just puts B zero?
What i have tried to do, was to say that 0 is in fact 0.00000000001. Then asta is starting from 1. But I dont know if the procedure is right. The plot is not as I expected :(
something is fishy
