C and D
Consider a function f(x) defined as follows:
.if 0<x<1
if 1<x<2
....
Answer the following questions without finding any series:
(2-a) Sketch the graph of the function represented by Sine Fourier series (SFS) of f(x) in the
interval (-6,+6)?
Hint: Assume that SFS has a period T = 4.
(2-b) To what values does SFS converge to at the following points: x = -2, -1, 0, +1, +2?
(2-c) Sketch the graph of the function represented by Cosine Fourier series (CFS) of f(x) in the
interval (-6,+6]?
(2-d) To what values does CFS converge to at the following points: x= -2, -1, 0, +1, +2?
