A similar structure can be observed in Figure 7 (surrender rate by curtate
duration) and, to a lesser extent, in Figure 6 (surrender rate by attained age).
Four special cases are, (1) If this component is positive, the trajectory is a curtate
cycloid; (2) If this component is negative, the trajectory is a prolate cycloid; (3) If this component is zero, the trajectory is a cycloid; and (4) If this component is equal to the electromagnetic drift velocity, the trajectory is a straight line; both the curvature and torsion of the path are zeros.
after the structure of transition state, the curtate
trend of the length is slow down, and the 2O-4H bond appeared, The length between atoms remains unchanged; at the same time, the length of 1C-4H is greatly elongated until the bond is broken.
According the relation between d and r we speak about a curtate
(contracted) cycloid (d < r) or about a prolate one (d > r).
In terms of the future curtate
lifetime K (x) at age x, the present value of benefits of 1 per year is an annuity for K(x) years:
Let us now illustrate this using the information about the insured most commonly used in life settlements: the medical underwriter has developed an estimate that the curtate
expectation of life for the individual whose policy is being settled is m years.
The random variable K (x) describes the remaining curtate
lifetime of an individual of age x.
the number of completed future years lived by (x), or the curtate
future lifetime of (x), where [?
