Recall that for discrete sequences the ts sample period (the time period between samples) is the reciprocal of the sample frequency fs. Write the equations, describing time-domain sequences for unity-amplitude cosine waves whose fo frequencies are

fo = fs/2, one-half the sample rate,
fo = fs/4, one-fourth the sample rate,
fo = 0 (zero) Hz
