i would need to solve the integral equation..(adsbygoogle = window.adsbygoogle || []).push({});

[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.
