Fourier transform

**Sleep60** · April 25th 2010, 10:44 PM

i solved it but i m not sure, can you check it please?

$<br /> f(x) = \sin (w_0t).\cos(w_0t)<br />$

Find $a_n,b_n...$

$a_n=0$

$b_n=(t/4)(\sin(cw_0(2-n)(t/2))-\sin(cw_0(2+n).(t/2)))$

You appear to be asking about Fourier series and not the Fourier transform.

Also as the $a_n$ 's and $b_n$ 's are constants as yours appears to depend on $t$ it cannot be right.
