2 Fourier Series
3 Background In the early nineteenth century, Joseph Fourier (1768-1830), while studying the problem of heat flow, developed a cohesive theory of such series. Consequently, they were named after him A function f ( x ) is said to have a period T or to be periodic with period T if for all x, f ( x + T) = f ( x ), where T is a positive constant. The least value of T > 0 is called the least period or simply the period of f ( x ).
