Consequently, verify that the temperature distribution in a one-dimensional rod (that we previously derived in class) could be expanded in terms of a Fourier sine series, if and only if both ends of the rod have a temperature of zero. 6. Show (using the de Moivre relations) that an alternate representation of the function, f(x) expressed as a Fourier series over an interval (-L, L ), i.e., f(x) ~ ) sin( ) cos( 1 1 L x n b L x n a a n n n n o is: f(x) ~ ) ( L x n i n n e c where ) ( 2 1 n n n b i + a c...
