(adsbygoogle = window.adsbygoogle || []).push({}); Fourier transforms. help!!!

hey! i am in high school, working on a project on discrete fourier transforms..

I have the formula: X(k)= E^{N-1}_{n=0}x(n)(cos(wnk)-isin(wnk))

where w=2pi/N.

My question is: how do you express x(n)?does it have an equation, or what?

I really need help with this, so please if anyone knows.."

THANK YOU!
