We will also define the odd extension for a function and work several examples finding the Fourier Sine Series for a function. WebJun 16, 2024 · Note that the series for F(t) is no longer a Fourier series as it contains the a0t 2 term. The antiderivative of a periodic function need no longer be periodic and so we should not expect a Fourier series. Rates of Convergence and Smoothness Let us do an example of a periodic function with one derivative everywhere. Example 4.3.6 Take the function
