2. Problem 5.29 5.29 (a) In the Gibbs phenomenon, after the first maximum there is a first minimum. Where is it?how big is the function there? What is the limit

of this point? That is, repeat the analysis of section5.7 for this minimum point. (b) While you're about it, what will you get for the limit of the sine integral, Si(0)? The last result can also be derived by complex variable techniques of chapter 14, Eq. (14.16). Ans: (2/n) Si(2n) = 0.9028
