Fourier Series is a representation of a signal with an orthonormal basis set such as sine and cosine or exponential functions. There are three types of Fourier Series.Trigonometric and Compact Fourier Series use sine and cosine functions as an orthonormal basis set and Exponential Fourier Series use complex exponentials as an orthonormal basis set.Fourier Series is simply a way to break down a signal into its components using a designated basis set.Orthogonal Vectors and Basis Sets leading up to Fourier Series are described with mathematical expressions here.There are many links to Fourier and other useful sites at the online materials page.
