24 Elias Moubayed - Sketch even and odd half-range extensions. Then determine the Fourier series for the odd version only. Give the formulas for The Fourier coefficients. Also give the first three terms of the Fourier series with all necessary numerical values. Ans: (2/Pi)sin((Pi)x/4) -(2/Pi)sin((Pi)x/2) +(2/(3Pi))sin(3(Pi)x/4) +. 23-29 HALF-RANGE EXPANSIONS Find (a) the Fourier cosine series, (b) the Fourier sine series. Sketch f(x) and its two periodic extensions. Show the details. 23.1 4 24. 2 A
