# FourierCosSeries

 FourierCosSeries gives the n-order Fourier cosine series expansion of expr in t. FourierCosSeriesgives the multidimensional Fourier cosine series of expr.
• The -order Fourier cosine series of is by default defined to be with and .
• The -dimensional Fourier cosine series of is given by with .
• The following options can be given:
