1.
Below function is defined for one period
a)
b)
f(x) =
1
9x
10
9
x
1
==x+
-9
10
9
-10 < x < -1
- 1<x< 1
1<x< 10
Sketch the function f(x) for a period.
Determine whether the function f(x) is even, odd or neither
and explain the reason.
c)
Not using any mathematical tools, manually compute the
first three non-zero terms of the Fourier Series for the
function f(x). Show the working steps and use the
appropriate half-range expansion if applicable.
