 Author Comment/Response Rainer 05/26/11 06:22am Hello I currently work on some Fourier transformations with mathematica and stumbled onto something strange while doing so. I started a new kernel/notebook and entered FourierTransform[Cos[p^2] Sin[p^2]/p, p, x] The solution was 1/2 I Sqrt[\[Pi]/2] FresnelC[x/(2 Sqrt[\[Pi]])] - 1/2 I Sqrt[\[Pi]/2] FresnelS[x/(2 Sqrt[\[Pi]])] and this seems right to me. In the next input I added an factor: FourierTransform[Cos[a p^2] Sin[p^2]/(p), p, x] Now the result was 0. If I assign a value to a, e.g. 1 or 2 I get a normal result but with a variable this transforms to zero. I also tried some Assumptions like making a real number or bigger then zero but nothing helped, the result is still zero. Has anybody an idea why mathematica sais this Fourier transform is zero with a prefactor? Thanks in advance Rainer P.S.: I'm working with mathematica 7.0.1.0. and on SUSE 11.3 URL: ,
