Choose the function f(t) ; −∞ < ? < +∞, for which a Fourier series cannot be defined.

(a) 3 sin(25t?) (b) 4 cos(20t? + 3) + 2 sin (10?t)

(c) e-|t| sin(25?t) (d) 1

fourier series are available for all periodic signal .its obvious that all the four are periodic.But somewhere i hear that fourier series is not possible for constant .could someone give me hint for the answer ,so try to come up. Thank you
