Fourier coefficients $x(t) = A_1 cos (2 pi f_0 t + E ) + A_3 cos (6 pi f_0 t + F )$

I applied the Fourier series definition with the integer from $0$ to $t * e^2if_0ktpi $ and I found that the series is $ 0 $ except for $k=1,-1,3,-3 $ but now I don’t know how to find the Fourier coefficients for this values of $k$.

  Thanks for trying to format your question! You just need dollar signs around the parts you want to format: $x(t)$ becomes $x(t)$.
