Figure 2.3 Solutions to equation (2.52) showing q(1,~) versus r, for 9 = 1, fo = 7 and
wf = 0.6: (a) the particular solution alone [Le. ffk = @k = 0 in equation (2.56)], which would
correspond to the steady-state solution if damping were included; (b) full solution for N = I;
(c) full solution for N = 2 (-) and N = 4 (. . .) on an expanded scale of r.
