Example 3:- find the fourier series for the function such that:-Solution:-We have 1 + 2 where 1 and 2 The Fourier coefficients of 2 are 0 except for Since 1 is an odd function, thus it will be represented by fourier sine series where. 23. 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. State the
