Hi All
I calculated two expressions:
FullSimplify[Integrate[(-L^2)/(L^2 + 1)*Cos[L], {L,0, Infinity}]]
and
FullSimplify[Integrate[(-1)/(L^2 + 1)*Cos[L], {L,0, Infinity}]]
They gave the same result, but in the first expression when we take
L->Infinity, it's impossible to take integral, but MAthematica CAN do that.
What the explanation of this?
Tnx for any help.
Ihor
