Hi, I'm having some trouble with the following integral: Making , then And if , then So Now, for the integral of : So So So I guess integration by parts won't do it here. How can I solve it?

convert i*e(it) to i*(cos(t) + i*sin(t) If you want to use by parts, set i*e(it)dt = du and sin(t)

Edit: Just figured it's better to express sin t as (1/2)(-ie^{it}+ie^{-it}) and the integral becomes so much easier.
