SUMMARY
The integral of the complex exponential function e^(ix) from 0 to infinity evaluates to -1/i, despite the oscillatory nature of the function. The upper limit of the integral approaches zero, which is a critical aspect of the evaluation. This conclusion is established through a specific proof that clarifies the behavior of the integral at infinity.
