A Fourier series is an expansion of a periodic function in terms of an infinite sum of sines and cosines.
Fourier series is a college-level concept that would be first encountered in an analysis course.
Prerequisites
| Power Series: | A power series is a sum of powers of a variable. A power series is essentially an infinite polynomial. |
| Taylor Series: | A Taylor series is a power series of a function around a given point. |
