Dear All,
Does Maple have built-in Finite Fourier Sine/Cosine Transformation which is defined as below?
2/L*int(f(x)*sin(n*Pi/L*x),x=0..L);

How can I get the finite Fourier transform for the derivatives of a function in terms of its own Fourier transform? 

I know that the fouriersin/fouriercos commands of the inttrans package have the Fourier sine/cosine transformation for the interval from x=0 to infinity?

Best wishes
