Given two periodic functions. f (t) and ,g (t) is defined by

(a) Sketch the graph of the periodic functions f (t) and g (t) over the interval [-3?, 3?]. Sketch in separate graphs.

(b) Find the Fourier series of f (t) and g(t).

Then, briefly comment what do you observe from the graphs and the Fourier series expansion of f(t) and g (t).

Transcribed Image Text:

f(t) = cos cos f(1) = f(1+2π) π f(t) = cos cos f(1) = f(1+2π) π
