John says that the value of the function cos[w(t + T) + j], obtained one period T after time t, is greater than cos(wt + j) by 2p. Larry says that it is greater by the addition of 1.00 to cos(wt + j). Which one, if either, is correct?
a. John, because wT = 2p.
b. John, because wT = 1 radian.
c. Larry, because wT = 2p.
d. Larry, because wT = 1 radian.
e. Neither, because cos(q + 2p) = cosq.
