This is essentially like telling you how strong different notes are in the music sound wave. The Laplace transform : k(t, u) =e−tu k ( t, u) = e − t u. This is handy for making certain differential equations easy to solve. The Hilbert transform : k(t, u) = 1 π 1 t − u k ( t, u) = 1 π 1 t − u.Laplace Transforms of Derivatives.
