老师，答案里假设one year forward rate 是3.5%的计算中，
1.为什么最后那个折现是e^3.5%*2 不应该是折到第一年末么 那应该是1+3.5%*1或者e^3.5%*1。
2.FRA不是使用单利么？这里不应该是复利吧？
问题如下图：

Whis the value of the FRA when the is just entere1、a forwarrate agreement (FRto receive a rate of 3.75%—这句话是不是说明这个FRA的利率是3.75%且我是short position？2、这题求t=1年时刻的value，我理解就是在t=2年时刻，用（3.75%—三个月市场的int）再折现到t=1年时刻，得出t=1年时刻的value，首先题目没有给出三个月市场的int，其次为什么value是0？3、题目答案写的计算的远期利率是3.75%，确实没错，但是这个远期利率也不是市场利率啊，怎么能说这个利率equto quoterate（FRA rate）呢，不理解
