Final answer:
The given function cannot be expanded into a complex Fourier series because it is not periodic.
Step-by-step explanation:
To expand the given function into a complex Fourier series, we need to interpret the function as periodic and express it as a sum of complex exponentials. However, the given function is defined only for 0 < x < 1 and 1 < x, which means it is not periodic.
Since the function is not periodic, we cannot expand it into a complex Fourier series.
Therefore, the number of terms required to have an accuracy of 99% in a Fourier series is not applicable in this case.
