Example 12.6.  Show that  [Graphics:Images/FourierTransformMod_gr_80.gif].  

 

Explore Solution 12.6.

Use the result of Example 12.5 and the symmetry property to find the Fourier transform.
Symmetry property.  If   [Graphics:../Images/FourierTransformMod_gr_85.gif]  then   [Graphics:../Images/FourierTransformMod_gr_86.gif].

Remark. Mathematica's  FourierTransform package does not use the same coefficient involving  [Graphics:../Images/FourierTransformMod_gr_91.gif]  as is commonly used in complex analysis.
