The colume V(in cubic feet) of water in a small reservior during spring runoff is given by the function V(t)=5000(t+1)^2 for t in months and 0

the flow rate (abbr.as R) equals to dV/dt,so
R(t)=dV/dt=10000(t+1)
R(0)=10000 (ft³/m)
R(2)=30000 (ft³/m)
V(t)=5000(t+1)^2=11250
so,t=1.5 (month)
R(1.5)=25000 (ft³/m)

对V(t)求导即为水流速度方程:10000(t+1),
因此t=0和t=2时的水流速度为10000 ft^3/month和30000 ft^3/month
库存量为11250时,根据V(t)方程可以求得t=0.5,再根据水流速度方程可知,此时的水流速度为15000 ft^3/month

这个程序里的孔的坐标是什么? 下面有人说:“就是求方程中无定义的那一点X的坐标(使分母等于零之类的) HOLE的话,是不是只有一个点没有定义呢?
