In Finite Fourier Cosine Transform, if the upper limit l = , then its inverse is given by ________

• A. (F(x) = frac{2}{ } _{p=1}^ fc (p)cos(px)+ frac{1}{ } fc(0) )
• B. (F(x) = frac{2}{ } _{p=1}^ fc (p)cos(px) )
• C. (F(x) = frac{2}{ } _{p=1}^ fc (p)cos( frac{px}{ }) )
• D. (F(x) = frac{2}{ } _{p=0}^ fc (p)cos(px)+ frac{1}{ } fc(0) )
