问题如下：
The six-month, 12-month, 18-month, and 24-month zero rates are 5%, 5.5%, 6%, and 6.5% (all measured with semi-annual compounding) respectively. What is the two-year par yield for a bond paying coupons every six months?
选项：
解释：
The par yield is the coupon rate c satisfying
It is 6.46%. Alternatively, we can use Equation . In
this case m= 2, d= 0.8799, and A= 3.7179.
A是怎么求得？看了讲义解释是1美元票息得年金价格？

NO.PZ2020021204000016 这道题是说一个2年的债券，每6，12，18，24个月的zero rate 不同吗？完全读不懂题，能不能吧题干拆解一下，讲解一下呢。谢谢
NO.PZ2020021204000016公示我用对了，小数点后保留4位计算也没算出来答案c的数值
