The Half-Range Fourier Series is a mathematical tool used to represent a function defined in a limited interval (typically \\(\[0, L\]\\)) in terms of simpler trigonometric functions. It is particularly useful for functions that are defined only on half of the standard periodic interval, such as \\(\[0, L\]\\) instead of the full interval \\(\[-L, L\]\\).
