    Be more specific. Cn is just a symbol that is highly context dependent. There is no standard meaning of Cn.

    The equation contains a sum of terms indexed by the integer n, and n ranges from 1 to infinity.

    Cn is the complex coefficient in term n.

    You can see similar notation in http://lpsa.swarthmore.edu/Fourier/Series/ExFS.html
