In mathematics , a trigonometric series is any series of the form:
[ 1]
It is called a Fourier series when the terms A n and B n
where f is an integrable function .[ 1]
It is not that case that every trigonometric series is a Fourier Series. A particular question of interest is given a trigonometric series, for which values of x does the series converge.
