Clearly, in the light of the observations presented above 
in § 115, and from relation (123-9), the expressions for C , 
C8, and C$, can be obtained by writing i=o0 in the preceding 
relations i.e. by putting u= -p. 
For 6=0, we have (relation 25

252-5) C(t) = —= Ra(t)=0.Ry 
which is relation (251-9) given above. 
Case of a Stationary Process 
253. The formulae corresponding to a stationary process 
can be deduced immediately from those just given by putting 
> =0. 
In this case, of course, we have
