Please answer the dotted blue question. Thank you

(a) Let x[nj be a real periodic signal with period N and Fourier coefficients ak. (i) Show that if N is even, at least two of the Fourier coefficients within one period of ak are real. (ii) Show that if N is odd, at least one of the Fourier coefficients within one period of ak is real. (b) Find the closed-form expression of the convolution of the sequences x(n) = (0.6)nu(n) and h(n) = (0.5)nu(n). (c) ) A system with input x(t) and output y(t) is defined by the equation y(t) = sin[x(t)]. Determine whether this system is invertible.
