Problem with integral

[Carsen]

I think the simplify command did a fine job. Since their was trig used in the answer of integral of e^(-t)*e^((-(i))*t), it probably attempted to keep the trig in the solution.

If the command trig2exp is used before simplify, it returns the answer in the same form as the first integral, which is...

Code:


((-1+i)*e^((-1-i)*τ/2)+(1-i)*e^((1+i)*τ/2))/2
