    Integrate this by splitting up the interval on which it is done:

    [tex]\int^L_{-L} f(t) dt = \int^L_{0} f(t) dt + \int^0_{-L} f(-t) dt [/tex]

    Then you'll be able to remove the '| |' and integrate it normally. When you're done with the integration, just substitute in the limits and let L approach infinity.
