(b)
Fig. 5-13

Comparing Fig. 5-13(b) and Fig. 5-10, we see that xf(r) in Fig. 5-13(b) is the same as x(r) in
Fig. 5-10 with A replaced by 2A/T0. Hence, from Eq. (5.111). replacing A by 2A/T0, we have

Equating Eqs. (5.119) and (5.1201, we have

From Fig. 5-1Na) and Eq. (5.6) we have

Substituting these values into Eq. (5.118), we obtain
