I would need to solve this

  1. Dec 9, 2006 #1
    i would need to solve the integral equation..:confused: :confused:

    [tex] g(x)=\int_{-\infty}^{\infty}dte^{ixf(t)} [/tex]

    the unknown function is f(t) g(x) is known, appart from using a numerical cuadrature method for the integral, what else can i do?.. could we prove if the function f(t) will exist or if it won't have any solution??..thanx.
