text: A Fourier series on [-L,L] is 2L periodic, and so are all its partial sums.
text: A series is convergent if the sequence of its partial sums ( S 1 , S 2 , S 3 , … ) {\displaystyle (S_{1},S_{2},S_{3},\dots )} tends to a limit; that means that the partial sums become closer and closer to a given number when the number of their terms increases.
