1. (a) Determine the Fourier cosine and Fourier sine series for cos on the interval (0, 2). (b) It can be shown that this Fourier cosine series converges on the closed interval 0, 2 and so converges to the even periodic extensions of cos with period 4. Determine the periodic extesions and sketch their graphs. (c) Also sketch the odd periodic extensions of cos where cos is defined on (0, 2).
