SUMMARY

The integral \(\int_{0}^{2\pi} e^{e^{ix}} dx\) can be effectively approached using Euler's formula. The transformation \(u = e^{ix}\) leads to the integral \(-i \int \frac{e^u}{u} du\). Mathematica from WolframAlpha provides a numerical approximation for this integral rather than a closed form involving special functions. For further insights, refer to the Exponential Integral documentation available at MathWorld.

I was trying to do this integral, this is not a homework question.

[tex] <br /> \int_{0}^{2\pi}e^{e^{ix}}dx[/tex]
I tried writing the e^(ix) part using eulers formula .
anyone have any other suggestions

I don't see other options than to express it using Euler's formula. As for the final result itself, the Mathematica software from wolframalpha.com returns a numerical approximation, not a combination of special functions.
