Consider the following function: f(x) = { sin x , if 0 ≤ x ≤ π 4 cos x , if π 4 ≤ x ≤ π 2 . Expand f(x) in a Fourier series of sine terms.
Question
Solution 1
The Fourier series of a function can be represented as a sum of sine and cosine terms. However, the function you provided is piecewise and defined differently in two intervals.
The Fourier series of a function f(x) is given by:
f(x) = a0/2 + Σ [an cos(nx) + bn sin(nx)]
