534. It is interesting to examine how the various parameters 
vary with changes in w and # when yc and ¢ - 0 are given by 
observation. 
For example, suppose that we have 
Yc=3.5 
1-0=4%, . 
lo calculate T and ©, we have the two relations (!) 
(534-1) 
(534-2) 
1m + wv 0 ~1-7_(i-p) 
1+T(i-p) [1+T (i-p)[" 
©,=[1-0w+wn]T 
Values of T and ©, 
535. The two following tables give the values of T and ©, 
for selected values of w and n (?). 
(") Relations (526-4) and (526-11). 
() When # increases indefinitely (a situation which is clearly of theo- 
retical interest only), three cases are nossible 
a) T does not tend to zero 
Then we have 
1+ T (i —p) 
- 68 
Chis relation defines the limit of T and .t implies 
o<w< Yo 32 
In this case wo is fairlv small.
