Absolute Exponential Integration

  1. Jun 4, 2013 #1

    What is the integration of the absolute value of e^ix? That is what is ∫|e^ix|^2 equal to? The whole absolute thing got me lost. Thanks in advance.

    For any real number x, [itex]|e^{ix}|= 1[/itex].

    What is the definition of ##e^{ix}##? And what is the definition of the ##|~~|##?
