comment Evaluating $\int_{a}^{\infty} \tfrac{(t-a)^2}{C^2} \cdot \exp ( - \tfrac{(t-a)^2}{C^2} ) \cdot \exp(iwt) \ dt$
Yes, the exercise I'm trying to solve actually asks me to Laplance transform this. I did however want to manually evaluate the integral.

Thanks a bunch, this seems to be perfect!

@Caran-d'Ache I actually did lose one. Can you tell me the Mathematica command you used to evaluate the integral?

comment Basic question about fractions
Thanks! The solution is $\tfrac{a}{a^2 - 2 b^2} + \sqrt{2} \tfrac{-b}{a^2-2b^2}$.

If you write your comment as an answer I can accept it...
