    Fourier transform

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

    $\displaystyle
    f(x) = \sin (w_0t).\cos(w_0t)
    $


    Find $\displaystyle a_n,b_n...$

    $\displaystyle a_n=0$

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

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

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