2. Show that the discrete-time sinusoid y[n] = cos(Non)u[n] can be generated using the simple difference equation y[n] - 2 cos(oly[n - 1] + y[n - 2] = 0 initialized using y(-1) = cos(20) and y[-2] = cos(200). This is useful for simple DSP chips that do not have a built-in cosine function, since the constant cos(20) can be precomputed.
