4. Half Range Fourier Series
Mar 10, 2020·4. Half Range Fourier Series. If a function is defined over half the range, say `0` to L, instead of the full range from `-L` to `L`, it may be expanded in a series of sine terms only or of cosine terms only.The series produced is then called a half range Fourier series.. Conversely, the Fourier Series of an even or odd function can be analysed using the half range definition.
