Order of integration and taking limits

[QUOTE="dyn, post: 6059481, member: 501581"] Hi. I came across the following integral in contour integration lim(ε→0) "integral of" exp(iaεe[SUP]iθ[/SUP]) dθ = θ If I take the limit first then it just becomes the integral of 1 which is θ. I have 2 questions - If I take the limit first and then perform the integral do I always get the same answer as when I do the integral first and then take the limit ? In other words does the order of operations matter ? If I wanted to do the integral first , how do I integrate the exponential of an exponential ? I have never seen one before. Thanks [/QUOTE]
