Get answer: Find the trigonometric polynomial F(x) of the form (2) for which the square
Chapter 11, Problem 11.1.115(choose chapter or problem)
Find the trigonometric polynomial F(x) of the form (2) for which the square error with respect to the given f(x) on the interval \(-\pi \leqq x \leqq \pi\) is minimum, and compute the minimum value for \(N=1,2, \cdots, 5\) (or also for larger values if you have a CAS).
\(f(x)=|\sin x|(-\pi<x<\pi)\)
Text Transcription:
-pi leqq x leqq pi
N = 1, 2, cdots, 5
f(x) = |sin x|(-pi < x < pi)
