320_Series_g_(Ch. 8 2680. Expand the function f(x) = ~ in sines of multiple arcs in the interval (0, n). Use the expansion obtained to sum the number series: Take the functions indicated below and expand them, in the interval (0, jt), into incomplete Fourier series: a) of sines of multiple arcs, b) of cosines of multiple arcs. Sketch graphs of the functions and graphs of the sums of the corresponding seiies in their domains of definition. 2681. f(x) x. Find the sum of the following series by means of the expansion obtained: I+P+P+... 2682. f(x) = x 2 . Find the sums of the following number series by means of the expansion obtained: 1) * +7)2+ 32+ i 2) 1 2683. f(x) = e ax . , 2684. /(*)= 1 when when -^ x when 0
Sec. 4\__Fourier Series _321 2690. 2691. / (x) = x sin x. when cos x when < x ^ ~ , cos x when Y 2693. Using the expansions oi the functions x and x* in the interval (0, it) in cosines of multiple arcs (see Problems 2681 and 2682), prove the equality 2694**. Prove that if the function /(x) is even and we have ?L + x} = f(~ x\ , then its Fourier series in the interval ( Ji, n) represents an expansion in cosines of odd multiple arcs, and if the function f(x) is odd arid /fy-f *) =/ (y~*) then in the interval ( Ji, Ji) it is expanded in sines of odd multiple arcs. Expand the following functions in Fourier series in the indicated intervals: 2695. f(x) = \x\ 2696. f(x)=*2x 2697. f(x) = e* ( !
