这个计算挺耗时的，请问可以用德州计算器计算这道题吗？
NO.PZ201701230200000101问题如下1. Baseon Exhibit 1, the five-yespot rate is closest to:A.4.4%B.4.45%C.4.5%B is correct. The five-yespot rate is termineusing forwarsubstitution anusing the known values of the one-year, two-year, three-year, anfour-yespot rates follows:这个推导能再讲一下吗？
NO.PZ201701230200000101 这个计算能不能通过计算器快速的计算出来，一个一个按就很容易出错
NO.PZ201701230200000101 4.45% 4.5% B is correct. The five-yespot rate is termineusing forwarsubstitution anusing the known values of the one-year, two-year, three-year, anfour-yespot rates follows: 这里怎么知道是考prate=coupon rate的特殊债券
4.45% 4.5% B is correct. The five-yespot rate is termineusing forwarsubstitution anusing the known values of the one-year, two-year, three-year, anfour-yespot rates follows: 为什么是=1，已经假设按照面值发行了吗。
我只想问五次开方是怎么按出来的。德州计算器。
