![5. Find the Fourier Coefficients for the following functions on the
given intervals:
(a) f(x) = x³
(b) f(x) = x³
[-n, 7]
[-1, 1)
0 -27 <x < -T
(c) f(x)=
1
-T < x < T
T <x < 2n
Notice: The L is 27 for this (and the next) function.
0 -27 < x < -T
{
}
(d) f(x) =
1
-T <x < T
T < x < 2n
Hint: What is different about this function and the previ-
ous function? How does that change things?
(e) f(æ) = {
-1 -T < x < 0
0 < x < T
}
