Best ResponseYou've already chosen the best response.0btw, you can write your question with the equation buttom, then you can copy the script and paste it to the question box, it will emerge as an equation :)

Best ResponseYou've already chosen the best response.1Fourier Series expansion for f(x) in [0,2pi] \(f(x)=a_0/2+\sum \limits_{n=1}^\infty a_n\cos nx+\sum \limits_{n=1}^\infty b_n\sin nx\) \[a_0=(1/\pi)\int \limits_0^{2\pi}f(x)dx\] \[a_n=(1/\pi)\int \limits_0^{2\pi}f(x)\cos nxdx\] \[a_0=(1/\pi)\int \limits_0^{2\pi}f(x)\sin nxdx\]
