ABSTRACT
In chapter 9 we defined the trigonometric Fourier series for a periodic, piecewise continuous function. That was an infinite series of the form
A0 + ∞∑
k=1 [ak cos(2piωk t) + bk sin(2piωk t)] .
Dealing with this series can be somewhat tedious. Typically, for example, the constant term, the cosine terms, and the sine terms must be computed separately.
