Question: Let f be a piecewise continuous function which is L-periodic. Let a be a real number, and define g(x) = f(x+a). In other words,

Let f be a piecewise continuous function which is L-periodic. Let a be a real number, and define g(x) = f(x+a). In other words, g is obtained from f by a translation to the left by a. Please show that the Fourier coefficients of g are given by (n): 2mina f(n). 2 =eL
