### Thank You Dr. Fourier

Recently, I noticed that there don't seem to be any Free (as in GNU) Fourier/Laplace/Z tables. Wikipedia has Integral Tables and (Wikipedia also has Fourier Tables (which aren't particularity useful because they use different normalization constants than I need) but what I envision is even more than that. I'd like to see Free tables where you can select specific and specific types of entries and export to LaTeX, MathML, PDF, PS, or rasterize to PNG at a given size. This would be a great tool for students. Does any one know of any free tables or have any thoughts on this?

As a final thought: u(t)\overset \mathcal{F} \longleftrightarrow \frac{1}{{j\omega }} + \pi \delta (\omega )

(and that too far to long to set)
