It is not clear but what you have in the attachment is it what you have after integrating? In this case simply evaluate at t and 0 and subtract.

If this is the integral let u = polynomial dv = exponential

you'll have to integrate more than once - Sep 23rd 2009, 12:19 PMe^(i*pi)
In addition to Calculus26's method I would bring out -1/4 outside the integral to clear the fraction if it is the integral
