Pi not PI. David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Eckhard Schlemm [mailto:e.schlemm at hotmail.de] To: mathgroup at smc.vnet.net Hello, I want Mathematica to calculate the FourierTransform of a function which is defined by Sin[x]^2 for Abs[x]<PI and zero else. I tried and defined the function g as follows: g[x_]:=If[Abs[x]>PI,0,Sin[x]^2]; That works fine. But if I have mathematica try to determine the FourierTransform by FourierTransform[g[x],x,p] I always get the error that the recursion limit and the iteration limit were exceeded... what am I'm doing wrong? Any help is appreciated thanks Eckhard -- _________________________ Ludwig Schlemm Tel: +49 (0) 160 91617114 LudwigSchlemm at hotmail.com
