what is the result of fourier transformation of functional theta [Heaviside] function?

Is it not the case -

[tex] \int_{-\infty}^\infty}\theta (a)e^{ikx}dx = \int_{a}^{\infty}e^{ikx}dx[/tex]

what you have written is fourier transforamtion of the "usual" theta function.
i would like to know how to transform theta function which in arguments have other function s [i.e. functional theta function].

True. Did you know there is a math area in the PF ? Just scroll the main page down.
