I really have no idea how to do this, please show some steps.

The discussion revolves around the integral of the argument of a complex expression, specifically \(\int arg(x^{ix} + x^{-ix}) dx\). The subject area includes complex analysis and integration techniques.
The discussion is ongoing, with participants raising questions about the assumptions made regarding the nature of \(x\) and the expression itself. Some guidance is offered regarding the complexities of defining the integral in the context of complex numbers, but no consensus has been reached.
There is mention of the potential complexity in defining the integral, particularly regarding the contour of integration and the nature of the complex powers involved. Additionally, one participant notes that this is not a homework problem, which may influence the approach taken in the discussion.
Dick said:If x is real the exp(ix)+exp(-ix) is real. Why? What is arg of a real number? Are you sure that's the whole problem?
