Use the fact that sin ? =???−?−??/ 2?( e raised to the power i t minus e raised to the power negative i t divided by 2i ) to evaluate ∫ ?2?sin 3??? ( e is raised to the 2 theta) without “looping”. Be sure to convert back to an expression involving real values only. Confirm that both methods produce the same result.
