Fourier Transforms
Fourier Transforms
(OP)
Does anyone know the proper way to get an Inverse Fourier Transform on mathcad? I am having trouble matching Mathcad's results with correct known values for other functions. Does anyone have a big list of fourier transforms??

If you are getting 'deltas' it sounds like the symbolic processor (uses the -> arrow to show results).
It can take more than a single moment to appreciate the distinction, especially as the symbolic processor can also do 'arithmetic'.
One thing that added to the confusion is the newer 'explicit' capability which uses (hidden) the symbolic substitution to show the intermediate results, and then at the end you use the numeric = to do the final calculation.
post a work sheet showing the example (use xmcdz without images or large results to keep the file size down). I'm normally in the http://collab.mathsoft.com/~Mathcad2000 forum.
