Sine integral (sinc integral) question

[redtree]

How might I find the integral solution for the following:

(Sorry for the poor notation)

$$\int$$sinc(4x*$$\sqrt{(1-2/x)}$$) dx from -$$\infty$$ to $$\infty$$

i find your writting a little bit ambiguous, what is 'sinc'?

Please see the following:

Put the argument of the sinc equal to u, then the integral becomes:

sin(u)/u 1/(du/dx)


Express du/dx in terms of u.
